TECHNICAL FIELD

The present disclosure relates to distributing network-based keys among entities in an electronic communication system.

BACKGROUND

Customers and service providers often must make transactions across secure telecommunication connections (e.g., a web browsing session or a telephone call). A connection between the customer and the service provider relies on authentication processes to validate the identity of the customer and the identity of the service provider before beginning an interaction between the customer and the service provider. Presently, each of such telecommunications connections between the customer and the service provider is initiated as if it were a first contact between the customer and the service provider. For example, when a customer uses the web browser to navigate to the service provider's website, the customer relies on the web browser to verify that the service provider's website is genuine before establishing an encrypted connection between the web browser and the service provider's website. After the web browser has validated the service provider's website, the web browser establishes an encrypted connection with the service provider's website. After the encrypted connection has been established, the customer sends personal identifying information, such as a username and a password, over the encrypted connection to confirm the customer's identity to the service provider's web site.

The process of browser-run authentication described above is complicated and requires many intermediate, often third-party, validation steps using certificates. The certificates are easy to falsify and therefore a risk that the validation process will be compromised is inherent in each step of the validation process. If the validation process is compromised, the encryption key, and therefore any information sent across the encrypted connection, may therefore be accessed by a hacker. Another drawback of the web browser-run verification process is that the service provider's website often uses the same encryption key to establish every encrypted connection with every web browser requesting a secure connection with the website of the service provider. Accordingly, if even a single communication between the service provider's website and the customer's browser is intercepted by a hacker, all subsequent communication for all customers occurring over telecommunication connections encrypted using the encryption key are compromised.

The customer may also make transactions with the service provider using a telephone call into a call center of the service provider. When the customer calls the call center of the service provider, the customer is required to validate his or her identity by providing personal identifying information, such as a birthdate, a social security number, an address, or historical family information to a call center employee. While the call center may thus verify an identity of the customer based on the personal identifying information provided, the customer has no way to verify that the call center employee is a genuine call center employee associated with the service provider. Furthermore, the customer has no way to prevent the call center employee from stealing the customer's personal identifying information.

In the examples described above, the customer and the service provider have a pre-existing relationship (e.g., the customer has already signed up for the service provided by the service provider), yet this pre-existing relationship is not leveraged to authenticate the customer during transactions that occur after the initial encounter between the customer and the service provider. Instead, the customer is required to provide many pieces of personal identifying information for every interaction between the customer and the service provider, as is described above for the customer calling the call center. Alternatively, the service provider may require the customer to make an account that is accessible by a username and a password with the service provider. The account includes the personal identifying information of the customer. However, since the validation process completed by the browser before establishing the encrypted connection has many points of weakness, meaning that information such as the username or the password sent by the user over the encrypted connection may be intercepted.

SUMMARY

This disclosure provides systems and methods for performing network-based key distribution operations in an electronic communication system.

The disclosure provides various methods for leveraging a pre-existing relationship between a first agent and a second agent to establish a secure communication channel between the first agent and the second agent. This secure communication channel is then leveraged to authenticate subsequent interactions between a user associated with the first agent and a user associated with the second agent without the exchange of personal identifying information of either of the users or either of the agents over a potentially vulnerable connection.

In one embodiment, the disclosure provides a method for leveraging a secure communication channel between a first agent and a second agent to authenticate an activity outside of the secure communication channel. The method includes establishing the secure communication channel by a method comprising: a first computing device generating a first absolute key for the first agent; generating a first partial relative key for the first agent; wherein the first absolute key and the first partial relative key define a relative identity of the first agent, wherein the relative identity is unique for a relationship between the first agent and the second agent; generating an intermediate key by taking a mathematical function, hash, or algorithm of the first absolute key, the first partial relative key, and a second partial relative key for the second agent; generating an encryption key by using a mathematical function, hash, or algorithm of the intermediate key and a second absolute key for the second agent; wherein the relative identity relationship is characterized by the encryption key, and the encryption key is used to encrypt subsequent communications between the first agent and second agent. Responsive to one of the first agent and the second agent receiving a request from the other of the first agent and the second agent to authenticate the activity outside of the secure communication channel, the method further includes authenticating the activity outside of the secure communication channel using the secure communication channel.

In another embodiment, the disclosure provides a method for leveraging a secure communication channel between a first agent and a second agent to authenticate an activity outside of the secure communication channel. The method includes receiving with the first agent a communication request through an insecure channel from the second agent. The method further includes receiving with the first agent an indicator of a relative identity relationship from the second agent. The method further includes sending with the first agent a request to authenticate the activity outside of the secure communication channel to the second agent. The method further includes authenticating the activity outside of the secure communication channel using the secure communication channel.

In another embodiment, the disclosure provides a system including a first computing device having at least a first processor and a first memory including a first key corresponding to a first agent. The system further includes a second computing device having at least a second processor and a second memory including a second key corresponding to a second agent. The first key and the second key form an encryption key establishing a relationship between the first agent and the second agent. The system further includes a third computing device having at least a third processor and a third memory including identifying data of a third agent. The first computing device, the second computing device, and the third computing device are in communication over a network. The first memory includes program instructions executable by the at least one processor of the first computing system to: retrieve, from the third computing device, the identifying data of the third agent; establish a secure connection with the second computing device by forming the encryption key; send at least a portion of the identifying data of the third agent to the second agent using the secure connection; request the second agent to authenticate the third agent; and responsive to receiving authentication of the third agent from the second agent: establish a second encryption key using identifying data of the first agent and the identifying data of the third agent; decompose the second absolute key into a third key and a fourth key using a mathematical algorithm; store the third key in the first memory; and send activation instructions for storing the fourth key into the memory of the third computing device instructions to the second computing device over the secure connection.

In another embodiment, the disclosure provides a method for establishing a relative identity relationship between a first agent and second agent, the method including a first computing device operable by a user and including a software application stored in a memory, the first computing device generating a first absolute key for the first agent. The method further includes generating a first partial relative key for the first agent. The first absolute key and the first partial relative key define a relative identity of the first agent based on an identity of the first computing device, an identity of the software application, and an identity of the user. The relative identity is unique for a relationship between the first agent and the second agent. The method further includes generating an intermediate key by taking a mathematical function, hash, or algorithm of the first absolute key, the first partial relative key, and a second partial relative key for the second agent. The method further includes generating an encryption key by using a mathematical function, hash, or algorithm of the intermediate key and a second absolute key for the second agent. The relative identity relationship is characterized by the encryption key, and the encryption key is used to encrypt subsequent communications between the first agent and second agent.

In another embodiment, the disclosure provides a method for leveraging a first secure channel of communication between a first agent and a second agent to create a second secure channel of communication between the first agent and a third agent. The method includes creating the first secure channel of communication between the first agent and the second agent using a configurable data-driven initial process on a first computing device. Responsive to the first agent receiving a request from the third agent to establish the second secure channel of communication, the method further includes retrieving identifying information from the third agent. The method further includes sending the identifying information from the third agent to the second agent over the first secure channel of communication. Responsive to receiving approval of the third agent's request from the second agent, the method further includes establishing the second secure channel of communication.

DETAILED DESCRIPTION

FIGS. 1 through 31, discussed below, and the various embodiments used to describe the principles of this disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of this disclosure may be implemented in any suitably arranged wireless communication system.

Before any embodiments of the disclosure are explained in detail, it is to be understood that the disclosure is not limited in its application to the details of construction and the arrangement of components set forth in the following description or illustrated in the following drawings. The disclosure is capable of other embodiments and of being practiced or of being carried out in various ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and should not be regarded as limiting. The use of “including”, “comprising”, or “having” and variations thereof herein is meant to encompass the items listed thereafter and equivalents thereof as well as additional items. As used herein, the word “may” is used in a permissive sense (e.g. meaning having the potential to) rather than the mandatory sense (e.g. meaning must).

Some portions of the detailed description which follow are presented in terms of algorithms or symbolic representations of operations on binary digital signals stored within a memory of a specific apparatus or special purpose computing device or platform. In the context of this particular specification, the term specific apparatus or the like includes a general purpose computer once it is programmed to perform particular functions pursuant to instructions from program software. Algorithmic descriptions or symbolic representations are examples of techniques used by those of ordinary skill in the signal processing or related arts to convey the substance of their work to others skilled in the art. An algorithm is here, and is generally, considered to be a self-consistent sequence of operations or similar signal processing leading to a desired result. In this context, operations or processing involve physical manipulation of physical quantities. Typically, although not necessarily, such quantities may take the form of electrical or magnetic signals capable of being stored, transferred, combined, compared, or otherwise manipulated. It has been proven convenient at times, principally for reasons of common usage, to refer to signals as bits, data, values, elements, symbols, characters, terms, numbers, numerals, or the like. It should be understood, however, that all of these or similar terms are to be associated with appropriate physical quantities and are merely convenient labels. Unless specifically stated otherwise, the terms “processing”, “computing”, “calculating”, “determining” or the like refer to actions or processes of a specific apparatus, such as a special purpose computer or a similar special purpose electronic computing device. In the context of this specification, therefore, a special purpose computer or similar special purpose electronic computing device is capable of manipulating or transforming signals, typically represented as physical electronic or magnetic quantities within memories, registries, or other information storage devices, transmission devices, or display devices of the special purpose computer or similar special purpose electronic computing device. The use of the variable “n” is intended to indicate that a variable number of local computing devices may be in communication with the network.

Referring now to FIG. 1, there is shown a block diagram of a system 100 in which trusted two-way authenticated communication channels may be established and used. The system 100 includes three computing devices 110, 120, 130 connected to a network 150. Although the system 100 has been shown with three computing devices, a scalable solution is described herein that can comprise additional computing devices.

The computing devices 110, 120, 130 are representative of a class of computing devices which may be any device with a processing unit and memory that may execute instructions. Computing devices may be personal computers, server computers, computing tablets, set top boxes, video game systems, personal video recorders, telephones, personal digital assistants (PDAs), portable computers, laptop computers, fax machines, cell phones and special purpose devices. Computing devices have processor and memory. These computing devices may run an operating system, including, for example, variations of the Linux, Unix, MS-DOS, Microsoft Windows, Palm OS, and Apple Mac OS X operating systems.

The network 150 provides a platform for communications between the computing devices 110, 120, 130. The network 150 may be or include local-area networks (LANs), wide-area networks (WANs), metropolitan-area networks (MANs), distributed networks and other similar networks in which computing devices may be linked together. The network 150 may provide lower layer network support for computing devices to interact with one another. The network 150 may be packet-switched and may comprise a common or private bi-directional network, and may be, for example the Internet. The network 150 may be wired or wireless. In addition, the network 150 may be configured based on client-server architecture, a peer-to-peer architecture, or any other distributed computing system architecture. Further, the network 150 may be configured to comprise additional components so as to ensure a scalable solution.

The computing devices 110, 120, 130 may include respective agents 115, 125, 135. The agents 115, 125, 135 may be securely bound to their respective computing devices 110, 120, 130. Alternatively, the agents 115, 125, 135 may be portable and installable on different computing devices at a user's discretion. For example, an agent or critical components thereof may be stored on a device such as a smart card or portable flash memory device, and a user may carry the smart card or portable flash memory device for use with various computing devices.

The agents of FIG. 1 are a first agent 115, a second agent 125, and a third agent 135. Although respectively shown with a single agent 115, 125, 135, the computing devices 110, 120, and 130 may each have more than one agent. As explained below, the agents 115, 125, 135 may have identities relative one another. The agents 115, 125, 135 may authenticate communication channels between the communications devices, and may provide security for communications on the authenticated channels.

As used herein, an agent may be or include a software module or application which may be loaded and run on a computing device. An agent may communicate with other functional units within the corresponding computing device. An agent may also communicate with agent's remote to the communications device. One function of an agent is to store certain encrypted data so as to prevent the encrypted data from being accessible (e.g., viewed) by other functional units within the computing device (e.g., applications in user space). Access may be considered restricted if the agent has exclusive access or substantially exclusive access to the tools needed to decrypt the packets, such as decryption keys and software. Access may also be considered restricted if the agent has exclusive access or substantially exclusive access to the encrypted data itself.

Encrypted data is data which has been obscured to make it unreadable and unidentifiable at some level of confidence. Data which has been encrypted can be decrypted using a corresponding method or algorithm which may correspond to the method or algorithm used to encrypt the data. This data may be or may be representative of, for example, numbers, characters, audio, images, voice and video.

The relative identity of one agent to another agent may be based on information which is unique for the relationship between the two agents. The relative identity also may be based on information which is only known to the two agents in the particular relationship. With multiple computing devices 110, 120, 130 and multiple agents 115, 125, 135, there may be multiple separate relative identities in the system 100. Thus, the first user agent has an identity relative to the second user agent and a different identity relative to the third agent. Likewise, the second user agent has an identity relative to the first user agent and a different identity relative to the third agent. Finally, the third user agent has an identity relative to the first user agent and a different identity relative to the second agent. All six of these relative identities may be distinct. In short, a relative identity uniquely identifies one particular agent's relationship to another particular agent.

Even between two agents, there may be multiple unique relative identities arising from multiple relationships between the two agents. For example, an individual may have a checking account and a savings account with the same bank. Those two accounts will have a separate account numbers. Likewise, the multiple relative identities created for two particular agents could identify the separate relationships the two agents have with each other.

Additional and fewer units, modules or other arrangement of software, hardware and data structures may be used to achieve the processes and apparatuses described herein.

Referring now to FIG. 2, there is shown a flow chart of an exemplary process of establishing a communication channel between two computing devices. The description of the process is made with respect to a first agent, termed agent A, hosted by a first computing device and a second agent, termed agent B, hosted by a second computing device. These agents may be, for example, the agents 115, 125, 135 in the system 100 of FIG. 1.

The process for establishing a communication channel between agent A and agent B is compose of two parts. The first part, from 210 to 240, establishes a relative identity relationship between agent A and agent B. A relative identity relationship means that agent A has a relative identity with respect to agent B and agent B has a relative identity with respect to agent A. Both agent A and agent B are aware of the existence of the relative identity relationship, but neither knows the relative identity of the other. In the second part of the process, from 250 to 290, each agent verifies the identity of the other before opening a secure trustworthy communication channel between agent A and agent B.

Either agent A or agent B may initiate the process to establish a relative identity relationship at 210. At 220, agent A defines its relative identity with respect to agent B. The relative identity of agent A may be obtained from a third party (not shown in FIG. 2), may be derived from information about the relationship between agent A and agent B, or may simply be randomly selected by agent A. Similarly, at 225, agent B defines its relative identity with respect to agent A. The relative identity of agent B may be also obtained from a third party, may be derived from information about the relationship between agent A and agent B, or may simply be randomly selected by agent B. Agent A and agent B may not disclose their relative identities to each other.

Either agent A or agent B may initiate subsequent communication at 250. At 260, agent A may send first information to agent B. The first information may be derived from the relative identity of agent A in a manner that allows agent B to verify the identity of agent A without disclosing the relative identity of agent A. The first information may be derived from the relative identity of agent A and other data known to both agent A and agent B.

Similarly, at 265, agent B sends second information to agent A. The second information may be derived from the relative identity of agent B in a manner that allows agent A to verify the identity of agent B without disclosing the relative identity of agent B. The second information may be derived from the relative identity of agent B and other data known to both agent A and agent B. The first and second information may be derived in numerous ways including using various algorithms well-known in the art of cryptography. For example, the first and second information can be generated by using one-way hash functions, modulus functions, cyclic arithmetic operations, and various other algorithms.

It should be recognized that the first and second information of this example may be distinct from each other. Additionally, both the first and second information are derived, in part, from the relative identities of agents A and B and are thus unique to the relationship between these two agents. While both the first and second information are derived, in part, from the relative identities of the agents A and B, respectively, the relative identities cannot be determined from the first and second information.

At 270, agent A uses the second information received from agent B to verify the identity of agent B. Similarly, at 275, agent B uses the first information received from agent A to verify the identity of agent A. A secure trustworthy communications channel is opened between agents A and B at 280 only if both agent A and B successfully verify the identity of the other agent. The process from 250 to 290 may be repeated for every communication session between agent A and agent B, or may be repeated only if secure trustworthy communications are desired between agents A and B. Communications between agents A and B, including communications required to verify their relative identities, may be encrypted using an encryption key. The encryption key may optionally be a unique key which may be defined at 230.

The communication channel that is established at 280 may be described as a secure communication channel because the identity information of either agent cannot be stolen. The identity information of an agent cannot be stolen because the identity information is not transmitted, provided or released from the agent over the network. As such, the identity of the agent is protected and is not compromised. As a result, fraudulent transactions based on using an agent's identity information are prevented since an agent's identity information cannot be obtained by an unauthorized entity.

The communication channel that is established at 280 may also be trustworthy. A trustworthy communication channel is a channel which is established between authorized entities. The communication channel of 280 is trustworthy since each agent has verified the identity of the other agent. The trust that is established and verified between the agents is based on the first and second information exchanged between the agents who, in turn, are derived from the relative identity of each agent.

FIG. 3 is a block diagram of another embodiment of a process to establish a relative identity relationship between two agents. The agents are again referred to as agent A and agent B. The process starts at 300 and ends at 380.

At 310, the agent A and agent B may be first authenticated to their respective computing devices. The agents may be authenticated to their respective computing devices in a number of ways, which may be the same or different for agent A and agent B. For example, when the local agent is under a user's control, the local agent may be authenticated using absolute identity information of the user. This could be, for example, a login ID and a password, and/or biometrics.

An agent may be authenticated to the computing device through relative identity. One technique for authenticating a user-controlled agent is to provide the computing device with an embedded master agent whose sole role is to interact with other agents installed in the computing device. Thus, for example, a user-controlled agent may authenticate itself to the embedded master agent based upon a relative identity between the user-controlled agent and the embedded master agent.

Either agent A or agent B may open a communication channel to the other agent at 320. At 330, a third party agent may optionally verify the identity of agent A and agent B and provide assurances to each agent of the identity of the other. The third party agent may be a specialized agent dedicated to verifying the identities of other agents on the network, or may be any agent that has established relative identity relationships with both agent A and agent B. The supervision of the third party agent is optional, and agent A and agent B may proceed to establish a relative identity relationship without third-party participation.

The process of FIG. 3 requires each agent to know or possess an absolute key and a partial relative key. Each agent's absolute key and the partial relative key may be obtained from an outside source (e.g., assigned to the agent) or may be generated within the agent. Keys may be generated using numerous techniques and algorithms. Agent A may acquire or generate a unique absolute key for each relationship between itself and other agents, including agent B. Agent A may have a single partial relative key used for all relationships, or may acquire or generate a unique partial relative key for each relationship with other agents. Similarly, agent B may have a unique absolute key for each relationship, and either a single partial relative key used for all relationships or a unique partial relative key for each relationship.

An agent's absolute key may not be transmitted or revealed to any other agent on the network. Not transmitting or revealing an agent's absolute key ensures that an agent's identity information cannot be stolen from transmission through the network since the identity information is not transmitted or revealed on the network. Since an agent has a unique absolute key for each relationship and the absolute keys are never transmitted or disclosed to other agents, each absolute key along with the partial relative key is equivalent to the relative identity of the agent for a specific relationship.

At 340 and 345, agents A and B exchange their respective partial relative keys. At 350, agent A forms a first intermediate key derived from agent A's absolute key and a function of the partial relative keys of both agent A and agent B. As previously described, the first intermediate key may be derived in numerous ways including using any of various algorithms or functions such as one-way hash functions, modulus functions, cyclic arithmetic operations, and various other algorithms. Similarly, at step 355, agent B forms a second intermediate key derived from its absolute key and a function of the partial relative keys of both agents. The first and second intermediate keys can be defined as follows:

Kn=f(a,q(c,d))=first immediate key, and

K12=f(b,q(c,d))=second immediate key

where:

-   -   a=absolute key of agent A;     -   b=absolute key of agent B;     -   c=partial relative key of agent A;     -   d=partial relative key of agent B; and     -   f and q are suitable functions or algorithms.

It should be recognized that the first and second intermediate keys of this example are distinct from each other. Additionally, both the first and second intermediate keys are derived, in part, from the partial relative keys of the local and remote agents and are thus unique to the relationship between these two agents. While both the first and second intermediate keys are derived, in part, from the absolute key of the agent that calculated the intermediate key, the absolute keys cannot be determined from the intermediate keys.

At step 360, agent A may form an encryption key KAB by combining agent A's absolute key with the second intermediate key received from agent B. The combination of agent A's absolute key with the second intermediate key may be done using the same function or algorithm used to form the intermediate keys. Similarly, at step 365, agent B may form an encryption key KBA by combining agent B's absolute key with the first intermediate key received from agent A. The combination of agent B's absolute key with the first intermediate key may be done using the same function or algorithm used to form the intermediate keys.

The function used to form the intermediate keys and the encryption keys may be an associative function, in which case the following relationship will hold:

KAB=f[a,f(b,q(c,d))]=f[b,f(a,q(c,d))]=KBA.

Thus both agent A and agent B may be in possession of an encryption key that may be used to encrypt subsequent communications between the agents. Moreover, since the encryption key can only be created through the use of the secret keys of both agents, the key cannot be recreated by either agent alone, or by any other party, even if the other party intercepts the partial relative keys and the intermediate keys during transmission between agent A and agent B. After the encryption key is formed, agents A and B may each discard the partial relative key and the intermediate key received from the other agent.

Agent A and agent B may then use the encryption key and their respective absolute and partial relative keys to authenticate one another at the start of subsequent communications. As shown in FIG. 4, an embodiment of a process for opening a secure trustworthy communication channel between agent A and agent B involves recreating the encryption key using information received from the other agent. The process for establishing a secure trustworthy communication channel starts at 400 and ends at 480. Optionally, the agents and users may be authenticated at 410 using the methods previously described in conjunction with step 310 in FIG. 3.

Either agent A or agent B may open a communication channel at 420. At 430 and 435, agent A and agent B exchange their respective partial relative keys. At 440 and 445, agent A forms and sends the first intermediate key, and agent B forms and sends the second intermediate key. The function or algorithm used to form the first and second intermediate keys may be the same as those employed when establishing the relative identity relationship between agent A and agent B (at 350 and 355 of FIG. 3). At 450 and 455, agent A and agent B recreate the encryption key. Recreating the encryption key may be performed using the function or process previously used when establishing the relative identity relationship between agent A and agent B (at 360 and 365 of FIG. 3).

At 460, agent A may compare the recreated encryption key from 450 with the known value of the encryption key. An exact match between the recreated and known encryption keys validates the identity of agent B to agent A. Similarly agent B may validate the identity of agent A at 465. A secure trustworthy communication channel may be opened between agent A and agent B at 470 only if both agents have successfully validated the identity of the other agent.

It must be noted that an impostor (e.g. Phisher) attempting to act as agent B must possess agent B's absolute and partial relative keys, as well as have knowledge of the functions or algorithms used to form the intermediate key and encryption key. In the optional situation where the communications between agent A and agent B are encrypted using the encryption key, the imposter would have to know the encryption key as well. Since the encryption key and the absolute key are never disclosed outside of the agent or transmitted over the network, the use of relative identity provides substantial protection against phishers and other impostors.

In the example illustrated in FIG. 5, either agent A or agent B is associated with a specific user having user identifying information 500, a specific computing device having device identifying information 504, and a specific software application having application identifying information 508. The term “user identifying information” is generally used to refer to personal identifying information associated with the user. Exemplary user identification may include a name, an address, a birthdate, a social security number, a user name, a password, or factual data about the user's life or family history. The term “device identifying information” is generally used to refer to identifying information associated with a specific computing device. Exemplary device identification information may include a serial number of the device, a type of the device (e.g. mobile phone, tablet, laptop computer), or an IP address of the computing device. The term “application identifying information” is generally used to refer to identifying information associated with a specific instance of the instance of the software application. Exemplary application identifying information may include a serial number of the software application, a version of the software application, and a type of device on which the application is programmed to run (e.g. a specific brand of computing device or a specific operating system of the computing device). Either agent A, agent B, or both agent A and agent B are associated with specific user identifying information 500, device identifying information, 504 or application identification information 508.

For example, in the embodiment illustrated in FIG. 5, agent A is associated with the user identifying information 500, the device identifying information 504, and the software application identifying information 508. A relative identity is then formed between agent A and agent B according to the method described in FIGS. 2 and 4. In either method, a portion of the user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying 508 information is shared with agent B in the process of forming the relative identity, and a portion of the user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying information 508 is not shared with agent B. For example, for processes requiring agent A to know or possess the absolute key 512 and the partial relative key 516 and requiring agent B to know or possesses the absolute key 520 and the partial relative key 524, the absolute key 512, the partial relative key 516, and the partial relative key 524 may all include the portion of the user identifying information, the portion of the device identifying information, and the portion of the application identifying information. Accordingly, after the relative identity relationship has been established between agent A and agent B, in order to establish the trusted two-way authenticated communication channel between agent A and agent B, the user, the computing device, and the instance of the software application attempting to open the trusted two-way authenticated communication channel between agent A and agent B must be the same as the user, the computing device, and the instance of the application used to establish the relative identity relationship between agent A and agent B.

Since the relative identity established by agent A and agent B is specific to the user, the computing device, and the instance of the software application used to establish the relative identity relationship, the encryption key created in terms of the relative identity relationship is unique to the specific relationship between agent A and agent B. Accordingly, agent A and agent B have a 1:1 authentication relationship. When agent A or agent B opens the trusted two-way authenticated communication channel, agent A or agent B refers to the relative identity relationship, for example by using a relationship identifier that is distinct from the encryption key. Agent A and agent B then recreate the encryption key using the relative identity relationship. Since the relative identity is specific to the software application used to initiate the relative identity relationship, after the initial configuration of the relative identity relationship, the trusted two-way authenticated communication channel may not be opened by a generic interaction between agent A and agent B, agent A and a third party, or agent B and the third party.

Either agent A or agent B may specify an amount of user identifying information 500, device identifying information 504, or software application identifying information 508 that must be used to establish the relative identity relationship. Relative identity relationships made using a relatively large amount of user identifying information 500, device identifying information 504, or software application identifying information 508 are more secure than relative identity relationships made using a relatively small amount of user identifying information 500, device identifying information 504, or software application identifying information 508.

In some embodiments, the relative identity relationship established between agent A and agent B as described above with respect to FIG. 5 may be used to authenticate an attempt by a third agent, agent C, to establish a relative identity with agent B or with agent A. In the embodiment of FIG. 6, agent A and agent C are associated with at least one of the same user or the same device. In such a method, agent B receives a request to establish the relative identity relationship from Agent C that includes the user identifying information 500, the device identifying information 504, and the application identifying information 508 corresponding to agent C (block 428). After receiving the request from agent C, the computing device associated with agent B identifies a match between at least one of the user identity information and the device identity information of agent A (block 432). Agent B then opens the trusted two-way authenticated communication channel using the previously-established relative identity relationship between agent A and agent B (block 436). After opening the trusted two-way authenticated communication channel, agent B sends a notification of agent C's request to establish the relative identity relationship to agent A and prompts agent A to confirm or deny agent C's request to establish the relative identity relationship (block 440). The notification sent by agent B to agent A over the trusted two-way authenticated communication channel includes the user identifying information 500, the device identifying information 504, and the application identifying information 508 sent with agent C's request. After receiving the notification sent by agent B, a user controlling agent A may confirm or deny agent C's request (block 446). If agent A approves agent C's request, agent B sends agent A notification that includes information for use in establishing the relative identity between agent B and agent C, such as an activation code or the partial relative key 524, to agent A using the trusted two-way authenticated communication channel (block 448). Agent A then provides the information for use in establishing the relative identity between agent B and agent C to agent C (block 452). Agent B and agent C then establish the relative identity relationship using the process described above in FIGS. 2 and 4 (block 456). If agent A denies agent C's request, the relative identity relationship is not formed between agent A and agent B (block 460). Accordingly, the trusted two-way authenticated communication channel between agent B and agent C may be authenticated without the use of a third-party authentication service or a third-party verification or certification service.

In some embodiments, the relative identity relationship established between agent A and agent B or agent C and agent B may be used to authenticate an attempt by a fourth agent, agent D, to establish a relative identity with agent B. As described above with respect to the authentication of agent C's attempt to establish a relative identity relationship with agent B, the previously-established relative identity relationship between agent A and agent B or agent C and agent B may be opened in response to a request from agent D to form a relative identity relationship with agent B. Accordingly, the trusted two-way authenticated communication channel between agent B and agent C may be authenticated without the use of a third-party authentication service or a third-party verification or certification service.

In some constructions, any of the instances of the software application may be operable to manage the relative identity relationships. For example, if a user is associated with several agents, for example agents A, C, and D that have relative identity relationships with another agent, such as agent B, the instance of the software application associated with one of agent A, agent C, or agent D may be used to remove relative identity relationships between agent B and the others of agent A, agent C, or agent D. In some constructions, the most recently established of the agents associated with a user such as, for example, agents A, C, or D associated with a user cannot be used to remove the agent that was used to confirm the most recently established agent's request to form a relative identity relationship with another agent, such as agent B.

In an exemplary embodiment involving the system of FIG. 5 and the method of FIG. 6, agent A may be a customer and agent B may be a bank. The customer downloads a first copy of the software application provided by the bank onto a first computing device having first device identity information. Each instance (e.g. copy) of the software application includes unique application identity information. When the customer opens the first copy of the software application for a first time, the first copy of the software application prompts the customer to enter the personal identifying information or the absolute identity information of the user. The customer then uses the first copy of the software application to request to establish the relative identity relationship with the bank. A portion of the user identifying information 500, the device identifying information 504, and the application identifying information 508 of the customer is sent to the bank. The bank sends information to the customer for use in establishing the relative identity relationship with the customer as described above with respect to FIGS. 2 and 4. For example, the customer's account number for a specific account in the bank may be used to generate the relative identity relationship. After the relative identity relationship between the customer and the bank is formed, the customer and the bank may use the software application to communicate using the trusted two-way authenticated communication channel. In some constructions, the user identifying information or the absolute identity information used to establish the relative identity between the customer and the bank is stored in a memory of the computing device associated with the customer and accessed by the first copy of the software application when the customer opens the secure communication channel. In other constructions, the user identifying information or absolute identity information used to establish the relative identity relationship between the customer and the bank is not stored on the first copy of the software application and must be entered the customer each time the trusted two-way communication channel is opened.

Since the relative identity relationship established between the customer and the bank is created using a portion of the user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying information 508, the trusted two-way authenticated communication channel can only be open if the user, the device, and the copy of the application used to initiate the attempt to open the trusted two-way authenticated communication channel are all the same as the user, the device, and the copy of the application are the same as were used to establish the relative identity relationship between the customer and the bank. For example, if the customer deletes the first copy of the software application from the first computing device and installs a second copy of the software application onto the first computing device, the customer cannot use the second copy of the software application to access the trusted two-way authenticated communication channel established using the first copy of the software application. Instead, the customer will be prompted to establish a new relative identity relationship with the bank when the user tries to use the second copy of the software application to open the trusted two-way authenticated communication channel. Similarly, a person other than the customer who established the trusted two-way authenticated communication channel attempts to the customer cannot use the first copy of the software application to access the trusted two-way authenticated communication channel established by the customer. Instead, the person other than the customer will be prompted to establish a new relative identity relationship with the bank when the person other than the customer tries to use open the trusted two-way authenticated communication channel.

Continuing with the present example, the customer may download a third copy of the software application onto a second computing device. When the customer opens the third copy of the software application for a first time, the third copy of the software application prompts the customer to enter personal identifying information or absolute identify information to the third copy of the software application. The customer then uses the third copy of the software application to request to establish a relative identity relationship with the bank. A portion of the user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying information 508 of the customer is sent to the bank and the bank sends information to the customer for use in establishing the relative identity relationship with the customer as described above with respect to FIGS. 2 and 4. Since the customer has a pre-existing relative identity relationship with the bank using the first copy of the software application and the first computing device, a portion of the user identifying information 500 sent in the third software application's request to establish a relative identity relationship will match a portion of the user identifying information 500 associated with the customer's existing relative identity relationship with the bank. After identifying the match between the request sent by the third copy of the software app and the customer, the bank opens the trusted communication channel between the customer, the first device, and the first copy of the software application (e.g. a pre-existing trusted two-way authenticated communication channel) and sends a notification of the third copy of the application's request to the customer over the pre-existing trusted two-way authenticated communication channel. The notification includes at least a portion of the user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying information 508 that the third copy of the software application included in the request to the bank. After receiving the notification sent over the pre-existing trusted two-way authenticated communication channel, the customer may approve or deny the request sent by the third copy of the software application. Since in this example, the request is a genuine request made by the customer, the customer approves the request included in the notification using the pre-existing trusted two-way communication channel. After receiving the customer's approval of the request, the bank sends the activation code or the partial key to the customer using the pre-existing trusted two-way communication channel. After receiving the activation code or the partial key from the bank, the customer may enter the activation code or the partial key into the third copy of the software application. After the customer has approved the request, the third copy of the software application and the bank establishes the relative identity relationship. When the request is not a genuine request made by the customer, the customer may deny the request included using the pre-existing trusted two-way communication channel, and a relative identity relationship is not established. In some constructions, the user identifying information 500, the device identifying information 504, and the application identifying information 508 may be retained by the bank.

In some embodiments, the pre-existing trusted two-way authenticated communication channel may be leveraged to authenticate requests made between agent A and agent B over an unsecured connection. Exemplary unsecured connections may include a web browser, a telephone to a call center, or an in-person interaction (e.g. between a customer and an employee of a service provider). As shown in FIG. 7, agent A and agent B may have the relative identity relationship that allows agent A and agent B to communicate using the trusted two-way authenticated communication channel. Agent A and agent B may also communicate using the unsecured connection. When agent A and agent B communicate using the unsecured connection, either agent A or agent B may use the pre-existing trusted two-way authenticated communication channel to request confirmation of instructions or a request made by agent A or agent B using the unsecured communication channel prior to following the instructions or responding to the request. In this manner, the pre-existing authenticated trusted two-way communication channel may be leveraged to validate the relative identity relationship between agent A and agent B without relying on third-party validation services or requiring personal identifying information or absolute identity information to be shared over the unsecured connection.

FIG. 8 illustrates a flowchart of an exemplary embodiment in which agent A may be a customer and agent B may be a bank. The customer has downloaded the software application provided by the bank onto the computing device. The customer has used the software application to establish the relative identity relationship with the bank. The relative identity has been established using a portion of the customer's user identifying information 500, a portion of the device identifying information 504, and a portion of the application identifying information 508 and the partial relative key 524 associated with the bank. Since the customer and the bank have established the relative identity relationship, the customer and the bank may use the software application to communicate using the trusted two-way authenticated communication channel.

In addition to communicating using the trusted two-way authenticated communication channel, the customer and the bank may communicate over an unsecured communication channel. For example, in the embodiment of FIG. 8, the unsecured communication channel is a phone call to a call center associated with the bank. As shown in FIG. 8, the customer establishes the unsecured connection by calling a telephone number associated with the bank (block 464). The customer's telephone call is answered by a call center employee (block 468). At the time that the customer's telephone call is answered, the customer has no verification that the person that answered the telephone call is an employee of the bank and the employee of the bank has no verification that the caller is actually the customer. Accordingly, after answering the telephone call, the employee of the bank may open the trusted two-way authenticated communication channel to for mutual verification between the customer and the bank (block 472). For example, the employee of the bank may send a confirmation request to the copy of the software application saved to the customer's mobile device requesting the customer authenticate that the call is genuine (block 476). The customer is prompted to accept or deny the authentication request (block 480). If the customer accepts the authentication request, the identity of both the customer and the bank are validated without the exchange of personal identifying information between the customer and the employee at the call center (block 484). If the customer denies the confirmation request, the call center employee is denied access to the customer's account information (block 488). In some embodiments, the notification sent to the customer is customizable. For example, in some embodiments, the employee of the bank introduces him or herself on the phone before sending the request. The notification sent to the customer would then include a name of the employee at the call center, so that the customer could have confirmation through the trusted two-way authenticated communication channel that the person on the phone call is actually an employee of the bank. For example, the notification may indicate the name and the location of the employee of the bank that was previously communicated to the customer during the phone call.

In some embodiments, the trusted two-way authenticated communication channel may be used to approve specific transaction made by the customer using the customer's account at the bank. For example, whenever a transaction using a credit card or a debit card is made by the customer, the bank may open the trusted two-way authenticated communication channel with the customer and send the customer a notification of the transaction. The notification requires the customer to approve or deny the transaction before the bank releases the funds for the transaction. In some embodiments, the customer may customize the transactions that require approval. For example, the customer may only require approval for transactions exceeding a predetermined amount of money. In some embodiments, the bank may customize the transactions that require verified approval. For example, the bank may require authenticated verification for any requests to transfer funds, add a new person to an account, change an address associated with the account, or change a beneficiary of the account. In such an embodiment, after receiving a request to transfer funds from the customer, the bank sends a notification to the copy of the software application saved on the customer's device using the trusted two-way authenticated communication channel. In some embodiments, the bank may customize the text of the notification for each transaction. For example, the confirmation request may include an account number from which the money will be withdrawn, an account number to which the money will be transferred, and an amount of money that will be transferred. In such an embodiment, the bank may save the customer's approval of the request to have an auditable trail of the transaction. Since the notification is sent to the customer before the transaction occurs, the customer has an additional opportunity to confirm that transaction request is correct. If the transaction request is incorrect, the customer may deny the confirmation request included in the notification before the money is transferred incorrectly. Furthermore, if the transaction included in the confirmation request is fraudulent, the customer may deny the transaction request before the money has been transferred to the thief.

In other embodiments, the trusted two-way authenticated communication channel may be used to confirm requests made between agent A and agent B using other types of unsecured communication channels. For example, in some embodiments, the unsecured communication channel may be a web browser, agent A may be a customer, and agent B may be a service provider that has a website accessible by a browser. In such an embodiment, agent A and agent B have established the relative identification as described above. Accordingly, before the user makes a transaction request from the service provider, the customer may leverage the trusted two-way authentication channel to confirm that the webpage is genuinely associated with the service provider before making a transaction. The customer or the service provider may also leverage the trusted two-way authenticated communication channel to confirm or deny service requests or transaction requests made using the browser without relying on third-party verification services.

In other embodiments, the unsecured communication channel may be an in-person interaction. In such an embodiment, agent A is a customer, and agent B is a service provider. The customer interacts in-person with the service provider through an employee of the service provider. In such an embodiment, the customer and the service provider have established a relative identity relationship as described above. Accordingly, when beginning an in-person interaction between the customer or the employee, the customer may leverage the trusted two-way authenticated communication channel to require the employee to confirm a relationship to the service provider. The employee may leverage the trusted two-way authenticated communication channel to confirm that the customer does have a relationship with the service provider without requiring the customer to provide any personal identifying information in a public setting.

In other embodiments, the unsecured communication channel may be a physical lock, such as a lockbox or a locked door. In such an embodiment, agent A is a user, and agent B the owner of the lock. In such an embodiment, agent A and agent B have established the relative identification as described above. Accordingly, when agent A requests access to the locked box or the locked door, agent A may leverage the existing two-way authenticated communication channel to send an access request to agent B to unlock the door. After agent B has approved the access request sent by agent A, the door may unlock. Agent B may also deny permission for agent A to unlock the door. In some constructions, the access request sent by agent A may be customized by agent B. For example, the access request sent by agent A may include an identity of the requester, a time and a data of the access request, and a location of the access request. Agent B may store the access requests from agent A and confirmation responses sent from agent B to agent A to have an auditable trail of agents that have requested access and agents that have been granted access.

As described herein, the computing system 935, utilizing the at least one processor 1205, is configured to execute one or more network-based key distribution operations. In certain embodiments, the computing system 935, utilizing one or more processors 1205, is configured to perform one or more network-based key distribution operations as described with reference to FIGS. 13-20 herein.

FIG. 13 illustrates a flow diagram of a method 1300 for network-based key distribution operations according to certain embodiments of the disclosure. Although certain details will be provided with reference to the method 1300 of FIG. 13, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1300 may be incorporated into one or more steps of method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, or one or more steps of method 2000 illustrated in FIG. 20

As described herein, an application 1105 to be installed in an electronic device memory of an electronic device 910 may be generated for storage and subsequent installation in the electronic device memory of the electronic device 910. One or more management servers 920 may generate a unique application key for the generated application 1105 and a universally unique identifier (UUID). The one or more management servers 920 may divide the unique application key into a server key (AK_(s)) and an encrypted client key (Enc-AK_(c)). The one or more management servers 920 may generate a client file (e.g., a REL-ID software development kit (SDK) 1107) and include the client encrypted key (Enc-AK_(c)) and the associated UUID in the client file. The management server 920 may embedded the client file in the application 1105 that is to be stored in the electronic device memory of the electronic device 910.

The one or more management servers 920 may also generate a corresponding server file containing the server key (AK_(s)) and the same UUID contained in the client file and transmit the server file to a credential store 1159 of the one or more credential stores 1159 for subsequent authentication described herein. After the client file is embedded in the application 1105 and the server file is stored in the credential store 1159, the electronic device 910 may download, receive, or install the application 1105 with the embedded client file and REL-ID SDK 1107 and store the client file and the REL-ID SDK 1107 in the electronic device memory.

At step 1301, one or more processors of the electronic device 910 may initially be in an idle state at least with respect to performing one or more network-based key distribution operations and subsequently transition to a startup state at least with respect to performing one or more network-based key distribution operations using the application 1105. The one or more processors may transition to the startup state, using the application 1105, at least with respect to performing one or more network-based key distribution functions after the application 1105 with the embedded client file is received by the electronic device 910 and stored on the electronic device memory of the electronic device 910. At step 1303, the one or more processors of the electronic device 910 retrieves, using the REL-ID SDK 1107, the encrypted client key and the UUID contained in the client file, for example, after the one or more processors transition to the startup state.

At step 1305, the one or more processors of the electronic device 910 may determine whether the electronic device 910 has been corrupted. For example, using a MTD Application Program Interface (API) 1109 of the client file, the one or more processors of the electronic device 910 may perform electronic device corruption detection (e.g., at least one of root detection, jailbreak detection, malware detection, or the like) to determine whether the electronic device 910 has been corrupted. The one or more processors of the electronic device 910 may perform electronic device corruption detection to generate an initial communication message for electronic transmission to the gateway 1155. Determining whether an electronic device 910 has been corrupted may prevent decrypted data, such as a decrypted client key, from being nefariously obtained after the one or more processors of the electronic device 910 decrypt the data and may prevent decrypted data, such as a decrypted client key, from being nefariously intercepted during transmission from the electronic device 910 to a gateway 1155 after the one or more processors of the electronic device 910 decrypt the data.

At step 1307, the one or more processors of the electronic device 910 may generate an initial communication message for electronic transmission to the gateway 1155 using the REL-ID SDK based on whether the one or more processors of the electronic device 910 determine that the electronic device 910 has been corrupted. In certain embodiments, when the one or more processors of the electronic device 910 determine that the electronic device 910 has been corrupted, the one or more processors of the electronic device 910 may generate an initial communication message that includes an error message. The error message may provide an indication to the gateway 1155 that network-based key distribution operations have been terminated. In certain embodiments, terminating network-based key distribution operations includes abstaining from decrypting the encrypted client key. Additionally, or alternatively, when the one or more processors of the electronic device 910 determine that the electronic device 910 has been corrupted, the one or more processors of the electronic device 910 may transition from the startup state to the idle state at least with respect to performing one or more network-based key distribution operations. In response to generating the initial communication message, the one or more processors of the electronic device 910 may electronically transmit the initial communication message to the one or more gateways 1155 using the REL-ID SDK.

In certain embodiments, when the one or more processors of the electronic device 910 determine using the MTD SDK 1109 that the electronic device 910 has not been corrupted, the one or more processors of the electronic device 910 may decrypt the encrypted client key and generate an initial communication message that includes the UUID contained in the client file. For example, the one or more processors may use the client file to decrypt the encrypted client key. The client file may contain a REL-ID SDK initialize API of the REL-ID SDK 1109 and use the REL-ID SDK initialize API of the REL-ID SDK 1107 to decrypt the encrypted client key. After decrypting the encrypted client key, the one or more processors of the electronic device 910 may transition from the startup state to an active state with respect to performing one or more network-based key distribution operations and generate, for transmission to the gateway 1155, an initial communication message that includes the UUID contained in the client file. In certain embodiments, the one or more processors of the electronic device 910 may generate an initial communication message includes the UUID contained in the client file. In response to generating the initial communication message, the one or more processors of the electronic device 910 may electronically transmit the initial communication message to the one or more gateways 1155. In certain embodiments, the one or more processors of the electronic device 910 electronically may transmit the initial communication message to the one or more gateways 1155 over an electronic communication channel that contains less security than a secured communication channel.

At step 1309, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may receive an initial communication message from an electronic device 910. For example, the computing system 935 of the gateway 1155 may be in an idle state at least with respect to performing one or more network-based key distribution operations. In response to receiving an initial communication message, the computing system 935 of the gateway 1155 may transition from the idle state to a startup state. The initial communication message may be received by the computing system 935 of the gateway 1155 from an electronic device 910 storing, in an electronic device memory, an application having an embedded client file containing a UUID as described herein. After receiving the initial communication message, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may determine whether the initial communication message includes an error message. When the computing system 935 determines that the initial communication message includes the error message, the computing system 935 may abstain from performing one or more network-based key distribution operations. In certain embodiments, the computing system 935 may also prevent the reception of electronic data from the electronic device 910 that transmitted the initial communication message.

When the computing system 935 of the gateway 1155 determines that the initial communication message includes the UUID, the computing system 935 of the gateway 1155 may obtain the UUID contained in the initial communication message. After obtaining the UUID, the computing system 935 of the gateway 1155 may access the credential store 1159 to obtain the server key associated with the same UUID. In certain embodiments, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may determine that at least one of the electronic device 910 or the received UUID are not authentic or not valid. For example, the one or more credential stores 1159 may store a table correlating individual server keys with different UUID. Each electronic device 910 may transmit a UUID specific to the application and thus, specific to the electronic device 910 to the computing system 935 of the gateway 1155. Each valid electronic device 910 may transmit a UUID to the computing system 935 of the gateway 1155 that matches a UUID stored in the one or more credential stores 1159. When the computing system 935 of the gateway 1155 receives the UUID in the initial communication message, the computing system 935 of the gateway 1155 may access the one or more credential stores 1159 containing the table that correlates UUIDs with server keys. The computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may determine that the UUID transmitted from the electronic device 910 is not authentic or not valid for secured data transmission between the electronic device 910 and the gateway 1155 when the transmitted UUID does not match a UUID contained in the table of the one or more credential stores 1159. Accordingly, the computing system 935 of the gateway 1155 may determine that at least one of the electronic devices 910 or the UUID are not authentic or not valid.

In certain embodiments, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may determine that the electronic device 910 and the received UUID are authentic or valid. For example, the one or more credential stores 1159 may store a table correlating individual server keys with different UUID. When the management server 920 created the unique application key and the UUID and divided the unique application key into the encrypted client key and the server key, the management server 920 may have stored the server key in the one or more credential stores 1159 and indicated in the one or more credential stores 1159 that the UUID is associated with or correlated with the server key. Thus, when the computing system 935 of the gateway 1155 receives the UUID in the initial communication message, the computing system 935 of the gateway 1155 may access the one or more credential stores 1159 and identify the server key associated with the UUID received from the electronic device 910 in the initial communication message and a UUID stored in the table of the one or more credential stores 1159. Accordingly, the computing system 935 of the gateway 1155 may determine that the electronic device 910 and the UUID are authenticated or valid.

At step 1311, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may retrieve the server key from the one or more credential stores 1159 that is associated with the UUID from the initial communication message. After retrieving the server key from the one or more credential stores 1159 and that is associated with the received UUID, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may initiate one or more secure channel protocols (e.g., an RMAK protocol) using both the server key to establish one or more secure channels (e.g., one or more RMAK secure channels) for data communication between the electronic device 910 and the gateway 1155. In certain embodiments, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate and transmit a coordination message to the electronic device 910. The coordination message may include one or more secure channel protocols (e.g., an RMAK protocol) to be performed by the electronic device 910 for establishing the one or more secure channels (e.g., one or more RMAK secure channels) with the gateway 1155.

At step 1313, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may receive the coordination message including the one or more secure channel protocols from the gateway 1155 using the REL-ID SDK 1107. At step 1315, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may initiate using the REL-ID SDK 1107 one or more secure channel protocols (e.g., an RMAK protocol) and establish one or more secure channels 1316 (e.g., one or more RMAK secure channels, one or more Application channels, one or more primary channels) in coordination with the computing system 935 of the gateway 1155 for data communication between the electronic device 910 and the gateway 1155. In certain embodiments, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may generate and transmit a confirmation message through the one or more established secure channels 1316 to the computing system 935 of the gateway 1155 confirming that the one or more secure channels have been established between the electronic device 910 and the gateway 1155 to securely transmit data.

At step 1317, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may receive the confirmation message from the electronic device 910 through the one or more secure channels 1316. After receiving the confirmation message from the electronic device 910 through the one or more secure channels 1316, at step 1319, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate and transmit an electronic device parameters request message through the one or more secure channels 1316. The electronic device parameters request message may include a request that the electronic device 910 identifies device parameters (e.g., variant device parameters, invariant device parameters) of the electronic device 910 and transmits the identified device parameters to the computing system 935 through the one or more secure channels 1316.

At step 1319, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may receive using the REL-ID SDK 1107 the electronic device parameters request message and identify the requested device parameters of the electronic device 910. After identifying the requested device parameters of electronic device 910, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may transmit the requested device parameters to the computing system 935 of the gateway 1155. In certain embodiments, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may transmit the requested device parameters to the computing system 935 of the gateway 1155 through the one or more secure channels 1316.

At step 1321, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may receive the requested device parameters of the electronic device 910 and perform one or more policy checks using the requested device parameters. The computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may execute the one or more policy checks using the requested device parameters to generate a device fingerprint associated with the electronic device 910. For example, the computing system 935 of the gateway 1155 may analyze the requested device parameters from the electronic device and perform the one or more policy checks to determine whether the requested device parameters passed the one or more policy checks. When the requested device parameters pass the one or more policy checks, the computing system 935 of the gateway 1155 may generate a device fingerprint associated with the electronic device 910. In certain embodiments, the computing system 935 of the gateway 1155 may access the one or more credential stores 1159 and retrieve device scope data privacy key, application scope data privacy key, and device and application scope data privacy key stored in at least one credential store 1159 of the one or more credential stores 1159. The device scope data privacy key, the application scope data privacy key, and the device and application scope data privacy key may support a data privacy API for execution by at least one of the computing system 935 of the gateway 1155 or the one or more processors of the electronic device 910.

At step 1323, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate an application session using the retrieved device scope data privacy key, application scope data privacy key, and device and application scope data privacy key. The computing system 935 of the gateway 155 may bind the application session to the generated device fingerprint associated with the electronic device 910. The computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate a session token and transmit the session token as well as the retrieved device scope data privacy key, application scope data privacy key, and device and application scope data privacy key to the electronic device 910.

At step 1325, the one or more processors of electronic device 910, performing one or more network-based key distribution operations, may receive using the REL-ID SDK 1107 the session token as well as the device scope data privacy key, application scope data privacy key, and device and application scope data privacy key from the computing system 935 of the gateway 1155. In certain embodiments, the session token as well as the device scope data privacy key, application scope data privacy key, and device and application scope data privacy key may be received by the one or more processors of electronic device 910 through the one or more secure channels 1316. At step 1327, the one or more processors of electronic device 910, performing one or more network-based key distribution operations, may via the application 1105 complete initialization using the received session token as well as the device scope data privacy key, application scope data privacy key, and device and application scope data privacy key from the computing system 935 of the gateway 1155.

At step 1329, the one or more processors of the electronic device 910, using the application 1105 and performing one or more network-based key distribution operations, may determine whether the electronic device 910 is to execute a self-registration protocol to create an identity associated with a user of the electronic device 910 or whether the electronic device 910 is executing the application and performing one or more network-based key distribution operations using a known identity associated with a user of electronic device 910. At step 1329, the one or more processors of the electronic device 910 may, using the application 1105, execute the self-registration protocol to create an identity associated with the user of the electronic device 910 when no known identity associated with the user of the electronic device 910 is identified. At step 1331, the one or more processors of the electronic device 910 may request, using the application 1105, a username when an identity associated with the user of electronic device 910 is identified. For example, the one or more processors of the electronic device 910 may initiate, using the application 1105, user identification flow. The one or more processors of the electronic device 910 may receive a username in response to display a request for a username on a display screen when a user already has a user account. In certain embodiments, the one or more processors of the electronic device 910 may store the username so that the user does not have to repeatedly provide the username to the electronic device 910 at subsequent occurrences. At step 1333, the one or more processors of the electronic device 910 may transmit, using the REL-ID SDK 1107, the username to the gateway 1155 through the one or more secure channels 1316.

At step 1335, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may receive the username from the electronic device 910 and access the one or more credential stores 1159 to check the user status as well as the application and device bindings. The computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may utilize a check-challenge API stored in a memory of the gateway 1155 to determine whether a user account is associated with the received username. For example, if the username is not associated with a user account, registration data may be requested from the electronic device 910 and subsequently transmitted from the electronic device 110 to the computing system 935 of the gateway 1155 using the one or more secure channels 1316. After receiving the registration data from the electronic device 910, computing system 935 of the gateway 1155 may transmit the registration data to at least one of the one or more management servers 920 or a backend business service of the business associated with the application stored in the memory of electronic device 910. As a result, a username may be generated allowing data transmission to connect back to the check-challenge API.

At step 1337, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may, using the check-challenge API, receive a user status from the one or more credential stores 1159. After the computing system 935 of the gateway 1155 receives a user status from the one or more credential stores 1159, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may request application and device keys from the one or more credential stores 1159. The computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may search for a key associated with the username and the application for the electronic device 910 (e.g., a device fingerprint). If the computing system 935 of the gateway 1155 does not find a key associated with the username and the application for the electronic device 910, the computing system 935 of the gateway 1155 may search the one or more credential stores 1159 to identify another key associated with the username and the application but that may be associated with another electronic device 910. If the computing system 935 gateway 1155 does not find another key associate with the username and the application, then at least one of the one or more processors of the electronic device 910 or the computing system 935 of the gateway 1155 may initiate an activation flow protocol to establish the username with the application and the electronic device 910. If the computing system 935 gateway 1155 does find another key associate with the username and the application, then at least one of the one or more processors of the electronic device 910 or the computing system 935 of the gateway 1155 may initiate a secondary device activation flow protocol to establish a username for the same application but with the current electronic device 910. If the computing system 935 of the gateway 1155 does find a key associated with the username and the application for the electronic device 910, then at least one of the one or more processors of the electronic device 910 or the computing system 935 of the gateway 1155 may initiate a normal login flow protocol.

FIG. 14 illustrates another flow diagram of a method 1400 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 14 illustrates an example method implemented by one or more processors of an electronic device 910, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 1400 of FIG. 14, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1400 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, or one or more steps of method 2000 illustrated in FIG. 20.

As described herein, an application 1105 to be installed in an electronic device memory of an electronic device 910 may be generated for storage and subsequent installation in the electronic device memory of the electronic device 910. One or more management servers 920 may generate a unique application key for the generated application 1105 and a universally unique identifier (UUID). The one or more management servers 920 may divide the unique application key into a server key (AK_(s)) and an encrypted client key (Enc-AK_(c)). The one or more management servers 920 may generate a client file (e.g., a REL-ID software development kit (SDK) 1107) and include the client encrypted key (Enc-AK_(c)) and the associated UUID in the client file. The management server 920 may embed the client file in the application 1105 that is to be stored in the electronic device memory of the electronic device 910.

The one or more management servers 920 may also generate a corresponding server file containing the server key (AK_(s)) and the same UUID contained in the client file and transmit the server file to a credential store 1159 of the one or more credential stores 1159 for subsequent authentication described herein. After the client file is embedded in the application 1105 and the server file is stored in the credential store 1159, the electronic device 910 may download, receive, or install the application 1105 with the embedded client file and REL-ID SDK 1107 and store the client file and the REL-ID SDK 1107 on the electronic device memory.

At step 1401, one or more processors of the electronic device 910 may initially be in an idle state at least with respect to performing one or more network-based key distribution operations and subsequently transition to a startup state at least with respect to performing one or more network-based key distribution operations using the application 1105. The one or more processors may transition to the startup state using the application 1105 at least with respect to performing one or more network-based key distribution functions after the application 1105 with the embedded client file is received by the electronic device 910 and stored on the electronic device memory of the electronic device 910. Step 1401 is at least similar to step 1301 of method 1300 illustrated in FIG. 13. At step 1403, the one or more processors of the electronic device 910 may retrieve the encrypted client key and the UUID contained in the client file using the REL-ID SKD 1107, for example, after the one or more processors of the electronic device 910 transition to the startup state using the application 1105. Step 1403 is at least similar to step 1303 of method 1300 illustrated in FIG. 13. At step 1405, the one or more processors of the electronic device 910 may determine whether the electronic device 910 has been corrupted using the MTD SDK 1109. Step 1405 is at least similar to step 1305 of method 1300 illustrated in FIG. 13.

At step 1407, the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may initiate a check application and device keys protocol using the REL-ID SDK 1107 to determine whether application and device keys from the one or more credential stores 1159 or a memory of the electronic device 910 exists. The one or more processors of the electronic device 910, performing one or more network-based key distribution operations, may search for a key associated with the username and the application for the electronic device 910 (e.g., a device fingerprint). At step 1409, the one or more processors of the electronic device 910 may search for and determine whether a key associated with the username and the application for the electronic device 910 exists using the REL-ID SKD 1107. If the one or more processors of the electronic device 910 do not find a key associated with the username and the application for the electronic device 910, then, at step 1411, the one or more processors of the electronic device 910 may activate a bootstrap flow protocol (e.g., an activation flow protocol, a server-side storage REL-ID flow protocol). If the one or more processors of the electronic device 910 do find a key associated with the username and the application for the electronic device 910, then, at step 1413, the one or more processors of the electronic device 910 may determine whether the key is locally authorized (e.g., authorized by the electronic device 910) or server authorized (e.g., authorized by the computing system 935 of the gateway 1155 or the management server 920) using the REL-ID SDK 1107. At step 1415, if the one or more processors of the electronic device 910 determine that the key is locally authorized (e.g., authorized by the electronic device 910), the one or more processors of the electronic device 910 may initiate a normal login-local authorization protocol. At step 1417, if the one or more processors of the electronic device 910 determine that the key is server authorized (e.g., authorized by the computing system 935 of the gateway 1155 or the management server 920), the one or more processors of the electronic device 910 may initiate a normal login-server-based authorization protocol.

FIG. 15 illustrates another flow diagram of a method 1500 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 15 illustrates an example method implemented by the computing system 935 of the gateway 1155 and the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. In certain embodiments, the method 1500 is directed to an activation flow protocol described herein. Although certain details will be provided with reference to the method 1500 of FIG. 15, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1500 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of method 1400 illustrated in FIG. 14, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, or one or more steps of method 2000 illustrated in FIG. 20.

At step 1501, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may transmit a message to the management server 1157 instructing the management server 1157 to generate credentials. At step 1503, the management server 1157 may receive the message from the gateway 1155 and generate a split key (e.g., a REL-ID split key, or user key (UK)). The management server 1157 may split the split key into two halves, a server key (UK_(s)) and a client key (UK_(c)). At step 1505, the management server 1157 may bind or associate the server key to the received username, the application 1105 stored in the electronic device memory of the electronic device 910, and the electronic device 910. The management server 1157 may bind or associate the server key to the application 1105 stored in the electronic device memory of the electronic device 910 based on the received UUID that is unique to the application 1105. The management server 1157 may bind or associate the server key to the electronic device 910 based on the device fingerprint.

At step 1507, the management server 1157 may generate an activation code and a validation code. The management server 1157 may use the activation code as entropy to generate a key that is subsequently to be used to encrypt the client key. At step 1509, the management server 1157 may encrypt the client key using the key generated using the activation code. At step 1511, the management server 1157 may transmit the activation code and the validation code out of band (e.g., via email, via text message) to the user of the electronic device 910. At step 1513, the management server 1157, after transmitting the activation code and the validation code out of band, may hash the activation code. The management server 1157 may store the hashed activation code and the validation code in a memory (e.g., a credential store 1159). At step 1515, the management server 1157 may transmit a request message to the electronic device 910 that requests the activation code and that includes the validation code. At step 1517, the computing system 935 of the gateway 1155 may receive the request message and transmit the request message using the one or more secure channels 1316. At step 1519, the one or more processors of the electronic device 910 may receive the request message using the REL-ID SDK 1107. At step 1521, the one or more processors of the electronic device 910 may receive the request for the activation code and the included validation code through the application 1105.

In certain embodiments, instead of generating an activation code, the management server 1157 may receive an activation code. The management server 1157 may use the provided activation code as entropy to generate a key that is subsequently to be used to encrypt the client key as described herein. This may be based on an enterprise application calling the “EnrollUser” API to generate REL-ID with a provided activation code. A usage scenario may include a customer wanting to use a knowledge based mechanism to unlock REL-ID such as using the last six digits of a user's credit card.

At step 1523, the one or more processors of the electronic device 910 may generate for display on a display screen the validation code for viewing and validation by the user through the application 1105. The one or more processors of the electronic device 910 may receive the activation code from the user (e.g., through a user interface). At step 1525, the one or more processors of the electronic device 910 may utilize the REL-ID SDK 1107 to hash the validation code with the received activation code. The one or more processors of the electronic device 910 may transmit the hashed validation code and activation code through the one or more secure channels 1316 to the gateway 1155. At step 1527, the computing system 935 of the gateway 1155 may receive the hashed validation code and activation code and validate the hashed validation code and activation code. For example, the computing system 935 of the gateway 1155 may instruct the management server 1157 to use the one or more credential stores 1159 to validate the hashed validation code and activation code.

At step 1531, when the hashed validation code and activation code are validated, the management server 1157 may transmit the encrypted client key to gateway 1155. At step 1533, the computing system 935 of the gateway 1155 may receive the encrypted client key from the management server 1157 and transmit the encrypted client key to the electronic device 910 using the one or more secure channels 1316. At step 1535, the one or more processors of the electronic device 910 may receive the encrypted client key and the activation code and decrypt the encrypted client key using the REL-ID SDK 1107. At step 1537, the one or more processors of the electronic device 910 may transmit a request through the application 1105 for user entropy (e.g., a password or a token) using the application 1105. At step 1539, the one or more processors of the electronic device 910 may receive or generate the user entropy using the application 1105.

In certain embodiments, the user entropy includes a biometric authenticator from the user, a password from the user, a passcode from the user, or a pin from the user. This process may also generate user entropy that may be recreated at each instance that the user authenticates using the authenticator. For example, when the user entropy includes a user password, passcode, or pin, the user entropy may be a hash value that is used as entropy. As another example, when the user entropy includes a touch ID or a face ID, the user entropy may be correlated with a random string that is generated and stored in at least one of the gateway 930, the management server 1157, or the credential store 1159. As another example, when the user entropy includes a server-based biometric, at least one of the management server 1157 or the gateway 1155 may transmit a value to be used as the user entropy to the electronic device 910. This value may be returned each instance that the user authenticates using the server-based biometric.

In certain embodiments, the one or more processors of the electronic device 910 may receive or generate the user entropy by registering the biometric or password. For example, the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may generate a random string and transmit the random string to a Fast Identity Online (FIDO) authenticator. The FIDO authenticator may register a user biometric and generate an asymmetric key pair (e.g., a private key and a public key). The FIDO authenticator may sign the random string using the private key and transmit the signed asymmetric key pair and the public key to the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107. The one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may validate the signed random string and save or store the signed random string and the public key. The one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may use the signed random string as user entropy.

At step 1541, the one or more processors of the electronic device 910 may re-encrypt the client key using the REL-ID SDK 1107 for storage (e.g., in an electronic device memory, a credential store 1159) using the entropy based on the user credential (e.g., password, token), the device scope key, and the application scope key. At this step, the one or more processors of the electronic device 910 may store the client key using the application 1105 in an electronic device memory and the computing system 935 of the gateway 1155 stores the server key (e.g., in a credential store 1159, in a memory of the gateway 1155). Thus, the one or more processors of the electronic device 910 may perform, using the REL-ID SDK 1107, an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910.

At step 1543, the computing system 935 of the gateway 1155 may perform an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910. In certain embodiments, the one or more secure channels 1542 may be user channels or secondary channels. At step 1545, the computing system 935 of the gateway 1155 may create a user session and bind the user session to a fingerprint associated with the user, the application 1105, and the electronic device 910. The computing system 935 of the gateway 1155 may transmit the user session to the electronic device 910. At step 1547, the one or more processors of the electronic device 910 may receive the user session from the gateway 1155 using the REL-ID SDK 1107. At step 1549, the one or more processors of the electronic device 910 utilizing the application 1105 may transmit and receive electronic data using the one or more secure channels 1542 to communicate with the computing system 935 of the gateway 1155 or the one or more management servers 1157 and the one or more credential store 1159 through the gateway 1155.

FIG. 16 illustrates another flow diagram of a method 1600 for network-based key distribution operations according to certain embodiments of the disclosure. In certain embodiments, the method 1600 is directed to a secondary device activation flow protocol described herein. Although certain details will be provided with reference to the method 1600 of FIG. 16, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1600 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, or one or more steps of method 2000 illustrated in FIG. 20.

In certain embodiments, the computing system 935 of the gateway 1155 may determine that a secondary device activation flow protocol is required. In certain embodiments, an activation flow protocol may have previously taken place on a new device being activated. At step 1601, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate and transmit a verify notification message (e.g., a REL-ID verify notification message) to another electronic device 910 that has been previously registered and bound. For example, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may generate and transmit a verify notification message (e.g., a REL-ID verify notification message) through an APPLE™ push notification service (APNS) or through Firebase Cloud Messaging (FCM) to another device 910 that has been previously registered and bound. At step 1603, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may save or store the verification notification message including the related electronic device 910 (e.g., the new electronic device) information and the information specific to the application 1105 on the electronic device 910. The computing system 935 of the gateway 1155 more store the verification notification message including the related electronic device 910 (e.g., the new electronic device) information and the information specific to the application 1105 on the electronic device 910 in one or more credential stores 1159.

At step 1605, the other electronic device 910 that was previously registered and bound using the application 1105 of the other electronic device 910 may receive the verification notification message. At step 1607, the one or more processors of the other electronic device 910 may use the verification notification message to display instructions using the REL-ID SDK 1107 to the user of the other electronic device 910 (e.g., the same user as the user of the electronic device 910) to perform a secure REL-ID authentication-then-connect flow protocol. For example, at step 1609, the one or more processors of the other electronic device 910 may transmit a request through the one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910. At step 1611, the computing system 935 of the gateway 1155 may receive the request from the other electronic device 910 and at step 1613, the computing system 935 of the gateway 1155 may transmit the verify notification message through the one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910 to the one or more processors of the other electronic device 910 utilizing the REL-ID SDK 1107. At step 1615, the one or more processors of the other electronic device 910 may receive the verify notification message.

At step 1617, the one or more processors of the other electronic device 910 may display the verify notification message on a display screen, utilizing the application 1105. For example, the one or more processors of the other electronic device 910 utilizing the application 1105 may use the verify notification message to ask the user via a display screen if the user is attempting to login on the electronic device 910 (e.g., a new electronic device 910). The one or more processors of the other electronic device 910 may utilize the verify notification message to ask the user via a display screen if the user is attempting to login on the electronic device 910 (e.g., a new electronic device 910). The one or more processors of the other electronic device 910 may utilize the verify notification message to ask the user via a display screen to provide relevant device information regarding the electronic device 910 (e.g., the new electronic device 910) that is captured from the device fingerprint (e.g., device type, device IP address, device location) and asks the user via a display screen to approve or reject the attempted login. At step 1619, the one or more processors of the other electronic device 910 may receive a reject response from the user and terminate the procedure. The one or more processors of the other electronic device 910 may receive an approve response from the user and transmit the approve response to the gateway 1155 through the one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910.

At step 1621, the one or more processors of the other electronic device 910 may receive the approve response and transmit the received approve response through the one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910 to the gateway 1155. At step 1623, the computing system 935 of the gateway 1155 may receive and store the received approved response in a memory of the gateway 1155 or in the one or more credential stores 1159. The computing system 935 of the gateway 1155 may transmit the received approve response to the one or more management servers 1157. At step 1625, the one or more management servers 1157 may receive the approve response and initiate the activation of the electronic device 910 (e.g., the new electronic device 910).

At step 1701, the management server 1157 may receive a message to activate an electronic device 910 (e.g., a new electronic device 910). At step 1703, the management server 1157 may generate a split key (e.g., a REL-ID split key, or user key (UK)). Step 1703 is at least similar to step 1503 of method 1500 illustrated in FIG. 15. At step 1705, the management server 1157 may bind or associate the server key to the received username, the application 1105 stored in the electronic device memory of the electronic device 910, and the electronic device 910. Step 1705 is at least similar to step 1505 of method 1500 illustrated in FIG. 15.

At step 1707, the management server 1157 may generate an activation code and a validation code. The management server 1157 may use the activation code as entropy to generate a key that is subsequently to be used to encrypt the client key. Step 1707 is at least similar to step 1507 of method 1500 illustrated in FIG. 15. At step 1709, the management server 1157 may encrypt the client key using the key generated using the activation code. Step 1709 is at least similar to step 1509 of method 1500 illustrated in FIG. 15. At step 1711, the management server 1157 may transmit the activation code and the validation code out of band (e.g., via email, via text message) to the user of the electronic device 910. Step 1711 is at least similar to step 1511 of method 1500 illustrated in FIG. 15. At step 1713, the management server 1157, after transmitting the activation code and the validation code out of band, may hash the activation code. The management server 1157 may store the hashed activation code and the validation code in a memory (e.g., a credential store 1159). Step 1713 is at least similar to step 1513 of method 1500 illustrated in FIG. 15.

At step 1715, the management server 1157 may transmit a request message to the electronic device 910 that requests the activation code and that includes the validation code. Step 1715 is at least similar to step 1515 of method 1500 illustrated in FIG. 15. At step 1717, the computing system 935 of the gateway 1155 may receive the request message and transmit the request message using the one or more secure channels 1316. Step 1717 is at least similar to step 1517 of method 1500 illustrated in FIG. 15. At step 1719, the one or more processors of the electronic device 910 may receive the request message using the REL-ID SDK 1107. Step 1719 is at least similar to step 1519 of method 1500 illustrated in FIG. 15. At step 1721, the one or more processors of the electronic device 910 may receive the request for the activation code and the included validation code through the application 1105. Step 1721 is at least similar to step 1521 of method 1500 illustrated in FIG. 15.

In certain embodiments, instead of generating an activation code, the management server 1157 may receive an activation code. The management server 1157 may use the provided activation code as entropy to generate a key that is subsequently to be used to encrypt the client key as described herein. This may be based on an enterprise application calling the “EnrollUser” API to generate REL-ID with a provided activation code. A usage scenario may include a customer wanting to use a knowledge based mechanism to unlock REL-ID such as using the last six digits of a user's credit card.

At step 1723, the one or more processors of the electronic device 910 may generate for display on a display screen the validation code for viewing and validation by the user through the application 1105. The one or more processors of the electronic device 910 may receive the activation code from the user (e.g., through a user interface). Step 1723 is at least similar to step 1523 of method 1500 illustrated in FIG. 15. At step 1725, the one or more processors of the electronic device 910 may utilize the REL-ID SDK 1107 to hash the validation code with the received activation code. The one or more processors of the electronic device 910 may transmit the hashed validation code and activation code through the one or more secure channels 1316 to the gateway 1155. Step 1725 is at least similar to step 1525 of method 1500 illustrated in FIG. 15. At step 1727, the computing system 935 of the gateway 1155 may receive the hashed validation code and activation code and validate the hashed validation code and activation code. For example, the computing system 935 of the gateway 1155 may instruct the management server 1157 to use the one or more credential stores 1159 to validate the hashed validation code and activation code. Step 1727 is at least similar to step 1527 of method 1500 illustrated in FIG. 15.

At step 1731, when the hashed validation code and activation code are validated, the management server 1157 may transmit the encrypted client key to gateway 1155.

At step 1741, the one or more processors of the electronic device 910 may re-encrypt the client key using the REL-ID SDK 1107 for storage (e.g., in an electronic device memory, a credential store 1159) using the entropy based on the user credential (e.g., password, token), the device scope key, and the application scope key. At this step, the one or more processors of the electronic device 910 may store the client key using the application 1105 in an electronic device memory and the computing system 935 of the gateway 1155 may store the server key (e.g., in a credential store 1159, in a memory of the gateway 1155). Thus, the one or more processors of the electronic device 910 may perform using the REL-ID SDK 1107 an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910.

Step 1749 is at least similar to step 1549 of method 1500 illustrated in FIG. 15.

FIG. 18 illustrates another flow diagram of a method 1800 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 18 illustrates an example method implemented by the computing system 935 of the gateway 1155, the one or more processors of the electronic device 910, and the one or more management servers 1157, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. In certain embodiments, the method 1800 is directed to an activation flow protocol described herein. Although certain details will be provided with reference to the method 1800 of FIG. 18, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1800 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1900 illustrated in FIG. 19, or one or more steps of method 2000 illustrated in FIG. 20.

The concepts described with respect to method 1800 of FIG. 18 may include changing the REL-ID key generation process so that the entire key is not generated by either the one or more processors of the electronic device 910 or the computing system 935 of the gateway 1155. Instead, both the one or more processors of the electronic device 910 and the computing system 935 of the gateway 1155 may each generate its own asymmetric key pair (e.g., a private key and a public key) and subsequently transmit its own respective public key to the other. After receiving each of the other's public keys, each of the one or more processors of the electronic device 910 and the computing system 935 of the gateway 1155 may generate and save its own respective REL-ID half key. As such, a full key pair (e.g., a whole REL-ID key) never exists with either the one or more processors of the electronic device 910 or the computing system 935 of the gateway 1155 at any time. Additionally, with this method, a client key does not have to be transmitted by the management server 1157 via the gateway 1155 to the one or more processors of the electronic device 910 improving security.

At step 1801, the computing system 935 of the gateway 1155 may initiate a bootstrap flow protocol and transmit a message to the management server 1157 to generate a server asymmetric key pair (e.g., a server public key and a server private key). At step 1803, the management server 1157 may receive the message from the gateway 1155 and generate the server asymmetric key having the server public key and the server private key. At step 1805, the management server 1157 may transmit the server public key to the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107. In certain embodiments, the management server 1157 may transmit the server public key through the one or more secure channels 1316 (e.g., the application channels) to the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107. At step 1807, the management server 1157 may receive the server public key through the one or more secure channels 1316 (e.g., the application channels) from the management server 1157. At step 1809, the one or more processors of the electronic device 910 may generate a client asymmetric key pair (e.g., a client private key and a client public key). At step 1811, the one or more processors of the electronic device 910 may generate a client REL-ID half key using the received server public key and subsequently save the client REL-ID half key. The one or more processors of the electronic device 910 may also transmit the client public key to the management server 1157 through the one or more secure channels 1316 (e.g., the application channels). At step 1813, the management server 1157 may receive the client public key. At step 1815, the management server 1157 may generate a server REL-ID half key using the received client public key. At step 1817, the management server 1157 may bind the server REL-ID half key to the user information, application information (e.g., UUID), and electronic device information associated with the electronic device 910 and save the server REL-ID half key, the user information, the application information, and the electronic device information associated with the electronic device 910 in the one or more credential stores 1159.

At step 1819, the management server 1157 may retrieve or receive and subsequently transmit the user information, the application information (e.g., UUID), and the electronic device information associated with the electronic device 910 saved in the credential store 1159 to the gateway 1155. At step 1821, the computing system 935 of the gateway 1155 may receive and subsequently transmit the user information, the application information (e.g., UUID), and the electronic device information associated with the electronic device 910 to the one or more processors of the electronic device 910 through the application channel 1316. At step 1823, the one or more processors of the electronic device 910 may receive the user information, the application information (e.g., UUID), and the electronic device information associated with the electronic device 910 from the gateway 1155 through the application channel 1316. At step 1825, the one or more processors of the electronic device 910 utilizing the application 1105 may receive the user information, the application information (e.g., UUID), and the electronic device information associated with the electronic device 910.

At step 1827, the one or more processors of the electronic device 910 may receive or generate the user entropy using the application 1105. Step 1827 is at least similar to step 1539 of method 1500 illustrated in FIG. 15. At step 1829, the one or more processors of the electronic device 910 may re-encrypt the client key using the REL-ID SDK 1107 for storage (e.g., in an electronic device memory, a credential store 1159) using the entropy based on the user credential (e.g., password, token), the device scope key, and the application scope key. At this step, the one or more processors of the electronic device 910 may store the client key using the application 1105 in an electronic device memory and the computing system 935 of the gateway 1155 may store the server key (e.g., in a credential store 1159, in a memory of the gateway 1155). Thus, the one or more processors of the electronic device 910 may perform using the REL-ID SDK 1107 an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910. Step 1829 is at least similar to step 1541 of method 1500 illustrated in FIG. 15.

At step 1831, the computing system 935 of the gateway 1155 may perform an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910. In certain embodiments, the one or more secure channels 1542 may be user channels or secondary channels. Step 1831 is at least similar to step 1543 of method 1500 illustrated in FIG. 15. At step 1833, the computing system 935 of the gateway 1155 may create a user session and bind the user session to a fingerprint associated with the user, the application 1105, and the electronic device 910. The computing system 935 of the gateway 1155 may transmit the user session to the electronic device 910 for example using a user session token. Step 1833 is at least similar to step 1545 of method 1500 illustrated in FIG. 15. At step 1835, the one or more processors of the electronic device 910 may receive the user session from the gateway 1155 using the REL-ID SDK 1107. Step 1835 is at least similar to step 1547 of method 1500 illustrated in FIG. 15. At step 1837, the one or more processors of the electronic device 910 utilizing the application may transmit and receive electronic data using the one or more secure channels 1542 to communicate with the gateway 1155 or the one or more management servers 1157 and the one or more credential store 1159 through the gateway 1155. Step 1837 is at least similar to step 1549 of method 1500 illustrated in FIG. 15.

FIG. 19 illustrates another flow diagram of a method 1900 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 19 illustrates an example method implemented by the computing system 935 of the gateway 1155 and the one or more processors of the electronic device 910, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure.

Although certain details will be provided with reference to the method 1900 of FIG. 19, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 1900 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, or one or more steps of method 2000 illustrated in FIG. 20.

At step 1901, the computing system 935 of the gateway 1155, performing one or more network-based key distribution operations, may transmit a message to the management server 1157 instructing the management server 1157 to generate credentials. Step 1901 is at least similar to step 1501 illustrated in FIG. 15. At step 1903, the management server 1157 may receive the message from the gateway 1155 and generate a split key (e.g., a REL-ID split key, or user key (UK)). The management server 1157 may split the split key into two halves, a server key (UK_(s)) and a client key (UK_(c)). Step 1903 is at least similar to step 1503 illustrated in FIG. 15. At step 1905, the management server 1157 may bind or associate the server key to the received username, the application 1105 stored in the electronic device memory of the electronic device 910, and the electronic device 910. The management server 1157 may bind or associate the server key to the application 1105 stored in the electronic device memory of the electronic device 910 based on the received UUID that is unique to the application 1105. The management server 1157 may bind or associate the server key to the electronic device 910 based on the device fingerprint. Step 1905 is at least similar to step 1505 illustrated in FIG. 15.

At step 1907, the management server 1157 may generate an activation code and a validation code. The management server 1157 may use the activation code as entropy to generate a key that is subsequently to be used to encrypt the client key. Step 1907 is at least similar to step 1507 illustrated in FIG. 15. At step 1909, the management server 1157 may encrypt the client key using the key generated using the activation code. Step 1909 is at least similar to step 1509 illustrated in FIG. 15. At step 1911, the management server 1157 may transmit the activation code and the validation code out of band (e.g., via email, via text message) to the user of the electronic device 910. Step 1911 is at least similar to step 1511 illustrated in FIG. 15. At step 1913, the management server 1157, after transmitting the activation code and the validation code out of band, may hash the activation code. The management server 1157 may store the hashed activation code and the validation code in a memory (e.g., a credential store 1159). Step 1913 is at least similar to step 1513 illustrated in FIG. 15.

At step 1915, the management server 1157 may transmit a request message to the electronic device 910 that requests the activation code and that includes the validation code.

At step 1921, the one or more processors of the electronic device 910 may receive the request for the activation code and the included validation code through the application 1105. Step 1921 is at least similar to step 1521 illustrated in FIG. 15.

In certain embodiments, instead of generating an activation code, the management server 1157 may receive an activation code. The management server 1157 may use the provided activation code as entropy to generate a key that is subsequently to be used to encrypt the client key as described herein. This may be based on an enterprise application calling the “EnrollUser” API to generate REL-ID with a provided activation code. A usage scenario may include a customer wanting to use a knowledge based mechanism to unlock REL-ID such as using the last six digits of a user's credit card.

At step 1923, the one or more processors of the electronic device 910 may generate for display on a display screen the validation code for viewing and validation by the user through the application 1105. The one or more processors of the electronic device 910 may receive the activation code from the user (e.g., through a user interface). Step 1923 is at least similar to step 1523 illustrated in FIG. 15. At step 1925, the one or more processors of the electronic device 910 may utilize the REL-ID SDK 1107 to hash the validation code with the received activation code. The one or more processors of the electronic device 910 may transmit the hashed validation code and activation code through the one or more secure channels 1316 to the gateway 1155. Step 1925 is at least similar to step 1525 illustrated in FIG. 15. At step 1927, the computing system 935 of the gateway 1155 may receive the hashed validation code and activation code and validate the hashed validation code and activation code. For example, the computing system 935 of the gateway 1155 may instruct the management server 1157 to use the one or more credential stores 1159 to validate the hashed validation code and activation code. Step 1927 is at least similar to step 1527 illustrated in FIG. 15.

At step 1931, when the hashed validation code and activation code are validated, the management server 1157 may transmit the encrypted client key to gateway 1155. Step 1931 is at least similar to step 1531 illustrated in FIG. 15. At step 1933, the computing system 935 of the gateway 1155 may receive the encrypted client key from the management server 1157 and transmit the encrypted client key to the electronic device using the one or more secure channels 1316. Step 1933 is at least similar to step 1533 illustrated in FIG. 15. At step 1935, the one or more processors of the electronic device 910 may receive the encrypted client key and the activation code and decrypt the encrypted client key using the REL-ID SDK 1107. Step 1935 is at least similar to step 1535 illustrated in FIG. 15. At step 1937, the one or more processors of the electronic device 910 may transmit a request through the application 1105 for user entropy (e.g., a password or a token) using the application 1105. Step 1937 is at least similar to step 1537 illustrated in FIG. 15. At step 1939, the one or more processors of the electronic device 910 may receive or generate the user entropy using the application 1105. Step 1939 is at least similar to step 1539 illustrated in FIG. 15.

In certain embodiments, the user entropy includes a biometric authenticator from the user, a password from the user, a passcode from the user, or a pin from the user. This process may also generate user entropy that may be recreated each instance that the user authenticates using the authenticator. For example, when the user entropy includes a user password, passcode, or pin, the user entropy may be a hash value that is used as entropy. As another example, when the user entropy includes a touch ID or a face ID, the user entropy may be correlated with a random string that is generated and stored in at least one of the gateway 930, the management server 1157, or the credential store 1159. As another example, when the user entropy includes a server-based biometric, at least one of the management server 1157 or the gateway 1155 may transmit a value to be used as the user entropy to the electronic device 910. This value may be returned each instance that the user authenticates using the server-based biometric.

In certain embodiments, the one or more processors of the electronic device 910 may receive or generate the user entropy by registering the biometric or password. For example, the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may generate a random string and transmit the random string to a Fast Identity Online (FIDO) authenticator. The FIDO authenticator may register a user biometric and generate an asymmetric key pair (e.g., a private key and a public key). The FIDO authenticator may sign the random string using the private key and transmit the signed asymmetric key pair and the public key to the one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107. The one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may validate the signed random string and save or store the signed random string and the public key. The one or more processors of the electronic device 910 utilizing the REL-ID SDK 1107 may use the signed random string as user entropy.

At step 1941, the one or more processors of the electronic device 910 may re-encrypt the client key using the REL-ID SDK 1107 for storage (e.g., in an electronic device memory, a credential store 1159) using the entropy based on the user credential (e.g., password, token), the device scope key, and the application scope key. At this step, the one or more processors of the electronic device 910 may store the client key using the application 1105 in an electronic device memory and the computing system 935 of the gateway 1155 may store the server key (e.g., in a credential store 1159, in a memory of the gateway 1155). Thus, the one or more processors of the electronic device 910 may perform using the REL-ID SDK 1107 an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to the user, the application 1105, and the electronic device 910. Step 1941 is at least similar to step 1541 illustrated in FIG. 15. At step 1943, the computing system 935 of the gateway 1155 may perform an RMAK protocol and generate or establish one or more secure channels 1542 that are specific and dedicated to at least one of the user, the application 1105, or the electronic device 910. In certain embodiments, the one or more secure channels 1542 may be user channels or secondary channels.

At step 1945, the computing system 935 of the gateway 1155 may create a user session and bind the user session to a fingerprint associated with the user, the application 1105, and the electronic device 910. The computing system 935 of the gateway 1155 may transmit the user session to the electronic device 910. Step 1945 is at least similar to step 1545 illustrated in FIG. 15. At step 1947, the one or more processors of the electronic device 910 may receive the user session from the gateway 1155 using the REL-ID SDK 1107. Step 1947 is at least similar to step 1547 illustrated in FIG. 15. At step 1949, the one or more processors of the electronic device 910 may generate a digital signing key (DSK), encrypt the DSK, and store the encrypted DSK in an electronic device memory of the electronic device 910. The one or more processors of the electronic device 910 may generate, encrypt, or store the DSK using the REL-ID SDK 1107. In certain embodiments, the one or more processors of the electronic device 910 may generate a public DSK when generating the DSK. For example, the generated DSK may be a DSK pair including a public DSK and a private DSK. The one or more processors of the electronic device 910 may encrypt the public DSK and store the private DSK in an electronic device memory of the electronic device 910. In some embodiments, the one or more processors of the electronic device 910 may encrypt the private DSK and store the encrypted private DSK in an electronic device memory of the electronic device 910. The one or more processors of the electronic device 910 may transmit (e.g., direct a transmission of) the generated public encrypted DSK over the user channel 1542 to the gateway 1155.

At step 1951, the computing system 935 of the gateway 1155 may receive the public encrypted DSK transmitted over the user channel 1542 from the electronic device 910. After receiving the public encrypted DSK, the computing system 935 of the gateway 1155 may verify or authenticate that the gateway 1155 has received a correct public encrypted DSK. When the computing system 935 of the gateway 1155 verifies or authenticates that the received public encrypted DSK is a correct public encrypted DSK, the computing system 935 of the gateway 1155 may transmit (e.g., permit the transmission of) the public encrypted DSK to the management server 1157 for storage in the one or more credential stores 1159. The management server 1157 may receive the public encrypted DSK from the gateway 1155 and store the received public encrypted DSK in the one or more credential stores 1159. In certain embodiments, when management server 1157 receives the public encrypted DSK from the gateway 1155, the management server 1157 may bind the public encrypted DSK to the fingerprint associated with the user, the application 1105, and the electronic device 910 and store the bound public encrypted DSK in the one or more credential stores 1159. After verifying or authenticating and subsequently storing the public encrypted DSK, the computing system 935 of the gateway 1155 may generate an authentication message indicating that the public encrypted DSK has been verified or authenticated (e.g., positively verified or positively authenticated) and stored or bound and stored in the one or more credential stores 1159.

At step 1953, the computing system 935 of the gateway 1155 may transmit (e.g., permit the transmission of) the authentication message indicating that the public encrypted DSK has been verified or authenticated to the electronic device 910 over the user channel 1542. At step 1955, the electronic device 910 may receive, through the REL-ID SDK 1107, the authentication message indicating that the public encrypted DSK has been authenticated or verified by the computing system 935 of the gateway 1155. At step 1957, the one or more processors of the electronic device 910 utilizing the application 1105 may transmit and receive electronic data using the one or more secure channels 1542 to communicate with the computing system 935 of the gateway 1155 or the one or more management servers 1157 and the one or more credential store 1159 through the gateway 1155. Step 1957 is at least similar to step 1549 illustrated in FIG. 15.

In some embodiments, the I/O interface 2115 may perform any necessary protocol, timing or other data transformations to convert data signals from one component (e.g., the system memory 2110) into a format suitable for use by another component (e.g., the processor 2105). In some embodiments, the I/O interface 2115 may include support for devices attached through various types of peripheral buses, such as a variant of the Peripheral Component Interconnect (PCI) bus standard or the Universal Serial Bus (USB) standard, for example. In some embodiments, the function of the I/O interface 2115 may be split into two or more separate components, such as a north bridge and a south bridge, for example. Also, in some embodiments some or all of the functionality of the I/O interface 2115, such as an interface to the system memory 2110, may be incorporated directly into the processor 2105.

The network interface 2120 may be configured to allow data to be exchanged between the computer system 2100 and other devices attached to the network 905 or between nodes of the computer system 2100. The network 905 may in various embodiments include one or more networks including but not limited to Local Area Networks (LANs) (e.g., an Ethernet or corporate network), Wide Area Networks (WANs) (e.g., the Internet), wireless data networks, some other electronic data network, a combination thereof, or the like. In various embodiments, the network interface 2120 may support communication via wired or wireless general data networks, such as any suitable type of Ethernet network, for example; via telecommunications/telephony networks such as analog voice networks or digital fiber communications networks; via storage area networks such as Fiber Channel SANs, or via any other suitable type of network and/or protocol.

The input/output devices 2125 may, in some embodiments, include one or more display terminals, keyboards, keypads, touchpads, scanning devices, voice, or optical recognition devices, or any other devices suitable for entering or accessing data by one or more the computer systems 2100. Further, various other sensors may be included in the I/O devices 2125, such as imaging sensors, barometers, altimeters, LIDAR, or any suitable environmental sensor. Multiple input/output devices 2125 may be present in the computer system 2100 or may be distributed on various nodes of the computer system 2100. In some embodiments, similar input/output devices may be separate from the computer system 2100 and may interact with one or more nodes of the computer system 2100 through a wired or wireless connection, such as over the network interface 2120.

As shown in FIG. 21, the memory 2110 may include program instructions 2130, which may be processor-executable to implement any element or action, as described herein. In one embodiment, the program instructions may implement at least a portion of methods described herein, such as the methods illustrated by FIGS. 13-20. In other embodiments, different elements and data may be included. Note that the data storage 2135 may include any data or information, as described herein.

Those skilled in the art will also appreciate that, while various items are illustrated as being stored in memory or on storage while being used, these items or portions of them may be transferred between memory and other storage devices for purposes of memory management and data integrity. Alternatively, in other embodiments some or all of the software components may execute in memory on another device and communicate with the illustrated computer system via inter-computer communication. Some or all of the system components or data structures may also be stored (e.g., as instructions, structured data) on a computer-accessible medium or a portable article to be read by an appropriate drive, various examples of which are described here. In some embodiments, instructions stored on a computer-accessible medium separate from the computer system 2100 may be transmitted to the computer system 2100 through transmission media or signals such as electrical, electromagnetic, or digital signals, conveyed via a communication medium such as a network and/or a wireless link. Various embodiments may further include receiving, sending, or storing instructions and/or data implemented in accordance with the foregoing description upon a computer-accessible medium. Generally speaking, a computer-accessible medium may include a non-transitory, computer-readable storage medium or memory medium such as magnetic or optical media, e.g., disk or DVD/CD-ROM, volatile or non-volatile media such as RAM (e.g., SDRAM, DDR, RDRAM, SRAM, or the like), ROM, or the like. In some embodiments, a computer-accessible medium may include transmission media or signals such as electrical, electromagnetic, or digital signals, conveyed via a communication medium such as network and/or a wireless link.

The network context 2200 may include one or more same or similar features of the network context 900 illustrated in FIG. 9 or described with respect to FIG. 9 or one or more same or similar features of the network context 1000 illustrated in FIG. 10 or described with respect to FIG. 10 or one or more same or similar features of the network context 1100 illustrated in FIG. 11 or described with respect to FIG. 11. One or more features of the network context 900 illustrated in FIG. 9 may be incorporated into or replace one or more similar features of the network context 1100 illustrated in FIG. 11 or described with respect to FIG. 11. Similarly, one or more features of the network context 2200 illustrated in FIG. 22 may be incorporated into or replace one or more similar features of the network context 900 illustrated in FIG. 9 or described with respect to FIG. 9. One or more features of the network context 1000 illustrated in FIG. 10 may be incorporated into or replace one or more similar features of the network context 2200 illustrated in FIG. 22 or described with respect to FIG. 22. Similarly, one or more features of the network context 2200 illustrated in FIG. 22 may be incorporated into or replace one or more similar features of the network context 1000 illustrated in FIG. 10 or described with respect to FIG. 10. One or more features of the network context 1100 illustrated in FIG. 11 may be incorporated into or replace one or more similar features of the network context 2200 illustrated in FIG. 22 or described with respect to FIG. 22. Similarly, one or more features of the network context 2200 illustrated in FIG. 22 may be incorporated into or replace one or more similar features of the network context 1100 illustrated in FIG. 11 or described with respect to FIG. 11.

As shown in FIG. 22, the network context 2200 includes one or more electronic devices 2210. At least one electronic device 2210 of the one or more electronic devices 2210 may store, in an electronic device memory, one or more applications 2201. The one or more applications 2201 may be the same as or similar to the application 1003 or the application 1009 illustrated in FIG. 10 or the application 1103, the application 1109, or the application 1113 illustrated in FIG. 11. As shown in FIG. 22, the electronic device 2210 may store a first application 2205 embedded with a REL-ID Mobile SDK protocol 2207 (the “client file 2207”) containing an encrypted client key uniquely associated with the first application 2205 and a UUID uniquely associated with the first application 2205. The electronic device 2210 may also store a second application 2209 embedded with a REL-ID Mobile SDK protocol 2211 (the “client file 2211”) containing an encrypted client key uniquely associated with the second application 2209 and a UUID uniquely associated with the second application 2209. The electronic device 2210 may further store an N^(th) application 2213 embedded with a REL-ID Mobile SDK protocol 2215 (the “client file 2215”) containing an encrypted client key uniquely associated with the N^(th) application 2213 and a UUID uniquely associated with the N^(th) application 2213.

The network context 2200 may also include one or more gateways 2255 (e.g., that is the same as or at least similar to the one or more gateways 930 illustrated in FIG. 9, that is the same as or at least similar to the one or more gateways 1055 illustrated in FIG. 10, or that is the same as or at least similar to the one or more gateways 1155 illustrated in FIG. 11), one or more management servers 2257 (e.g., that is the same as or at least similar to the one or more management servers 920 illustrated in FIG. 9, that is the same as or at least similar to the one or more management servers 1063 illustrated in FIG. 10, or that is the same as or at least similar to the one or more management servers 1157 illustrated in FIG. 11), and one or more credential stores 2259 (e.g., that is the same as or at least similar to the one or more credential stores 925 illustrated in FIG. 9, that is the same as or at least similar to the one or more credential stores 1067 illustrated in FIG. 10, or that is the same as or at least similar to the one or more credential stores 1167 illustrated in FIG. 11). The one or more credential stores 2259 may contain one or more tables 2263 storing UUIDs and associated server keys. For example, as shown in the table 2263, UUID-1 is the same UUID contained in the first application 2205, UUID-2 is the same UUID contained in the second application 2209, and the UUID-N is the same UUID contained in the N^(th) application 2213. Matching a UUID contained within an application with a same UUID contained in the table 2263 may allow for matching an encrypted client key contained in the application with the correlating server key listed with a matched UUID in the table 2263. In certain embodiments, the management server 2257 may be in electronic communication with the credential store 2259 via one or more communication channels 2261.

In certain embodiments, the network context 2200 may also include a secured area 2220. The secured area 2220 may be the same as or at least similar to the secured area 1050 illustrated in FIG. 10 and described with respect to FIG or the same as or at least similar to the secured area 1120 illustrated in FIG. 11. The secured area 2220 may include a demilitarized zone (DMZ) 2251 and a secured zone (SZ) 2253. The secured area 2220 may be a data center (e.g., on-prem, a cloud). For example, the gateway 2255 may be located in the DMZ 2251 while the management server 2257 and the credential store 2259 may be located in the SZ 2253. In certain embodiments, electronic communication between the one or more electronic devices 2201 and management server 2257 and the credential store 2259 in the SZ 2253 may communicate through one or more communication channels that pass through at least a portion of the DMZ 2251. For example, the gateway 2255 located in the DMZ 2251 may facilitate or control electronic communication between the one or more electronic devices 2210 and the management server 2257 located in the SZ 2253. In certain embodiments, the DMZ 2251 may include one or more firewalls 2256 intercepting electronic communication between the one or more electronic devices 2210 and the gateway 2255. In certain embodiments, the SZ 2253 may include one or more firewalls 2266 intercepting electronic communication between the gateway 2255 and the management server 2257. As described further herein, RMAK protocol flows 2271, 2273, 2275 (e.g. a secure application-specific tunnel/channel) may be established to provide communication between each of the applications 2205, 2209, and 2013, respectively, on the electronic device 2210 and the gateway 2255. Each of the RMAK protocol flows 2271, 2273, 2275 may provide communication through the firewall 2256 on the DMZ 2251.

The embodiments described herein may include REL-ID key generation, distribution, and use in a manner that is both secure and user-friendly, addressing challenges to cryptographic key based authentication systems. When a new mobile application leveraging REL-ID is being developed, a login (e.g., a username and password) (e.g., from an administrator) is provided into a REL-IDserver Administration Console (e.g., the management server 2257) to register the application. When the application is registered, an application identifier (e.g., an application UUID) and a split key (e.g., an application key) are created. The REL-IDserver Administration Console retains the server-half of the split key (AK_(s)) and provides the administrator within an encrypted blob which contains the client half of the split key (AK_(c)-Enc). The application key contains the application identifier (e.g., an application UUID, a GUID) used to identify the specific application version of the application among all other applications. The administrator may embed the client half of the split key with an application key (as part of the application manufacturing process) in the application (e.g., the application 2205, 2209, or 2213). The application will subsequently get distributed to users through an application store, play store, or another similar mechanism.

In certain embodiments, the client half of the key (AK_(c)) may be generated during an application registration process (e.g., as described herein), and may be encrypted using a symmetric key that is burnt into the client file 2207 (e.g., REL-ID SDK) and part of the REL-ID server to create the AK_(c)-Enc. This encrypted blob may be provided to an application developer to embed the encrypted blob in application code according to the application developer's standard best practices. The server half of the key of the application key (e.g., the split key) may be stored in the credential store 2259 (e.g., REL-ID credential store), encrypted (following standard enterprise security practices) using an asymmetric key having a private key that is stored securely in a JKS compliant key-store (usually an enterprise hardware security module, or HSM).

By default, the REL-ID SDK may leverage the secure hardware storage mechanism available on an electronic device (e.g., a secure element on an iOS device, TEE on an Android device) to securely store the client half of the key (e.g., a user key) (e.g., UK_(c)). The REL-ID SDK also has the ability to detect when an electronic device does not have a functioning and reliable secure hardware storage mechanism available (e.g., a combination of known platforms and OS versions, and some defensive coding strategies). When the REL-ID SDK determines that secure hardware storage is not available on an electronic device, the REL-ID SDK may alternatively encrypt the UK_(c) using a key based on user entropy (e.g., tied to a biometric authentication, tied to a password-based authentication) and a PBKDF2 algorithm and store the UK_(c)-Enc in the credential store 2259 (e.g., the REL-ID Credential Store) retrieved and used as described herein. In certain embodiments, the client half of the key (e.g., the user key) may be stored encrypted on the server-side, but the keys to decrypt the key are not stored anywhere on the server-side to provide a more secure storage for the client half of the key (e.g., the user key) that avoids the limitations of the electronic device in use while maintaining separation of data and keys.

FIG. 23 illustrates another flow diagram of a method 2300 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 23 illustrates an example method 2300 implemented by one or more processors of an electronic device 2210, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2300 of FIG. 23, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2300 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

As described herein, an application 2205 containing a client file 2207 (e.g., a REL-ID SDK protocol) to be installed in an electronic device memory of an electronic device 2210 may be generated for storage and subsequent installation in the electronic device memory of the electronic device 2210. One or more management servers 2257 may generate a unique application key for the application 2205 containing the client file 2207 and a universally unique identifier (UUID). The one or more management servers 2257 may divide the unique application key into a server key (AK_(s)) and an encrypted client key (AK_(c)-Enc). The one or more management servers 2257 may generate a client file (e.g., a REL-ID software development kit (SDK) 2207) and include the client encrypted key (AK_(c)-Enc) and the associated UUID in the application 2205. The management server 2257 may embed the client file in the application 2205 that is to be stored in the electronic device memory of the electronic device 2210.

The one or more management servers 2257 may also generate a corresponding server file containing the server key (AK_(s)) and the same UUID contained in the client file and transmit the server file to a credential store 2259 of the one or more credential stores 2259 for subsequent authentication described herein. After the client file is embedded in the application 2205 and an associated server file is stored in the credential store 2259, the electronic device 2210 may download, receive, or install the application 2205 with the embedded client file 2207 (e.g., the REL-ID SDK) and store the client file on the electronic device memory.

At step 2301, one or more processors of the electronic device 2210 may initially be in an idle state at least with respect to performing one or more network-based key distribution operations and subsequently transition to a startup state at least with respect to performing one or more network-based key distribution operations using the application 2205 containing the client file 2207 (e.g., the REL-ID SDK). The one or more processors may transition to the startup state using the application 2205 containing the client file 2207 at least with respect to performing one or more network-based key distribution functions after the application 2205 with the embedded client file 2207 is received by the electronic device 2210 and stored on the electronic device memory of the electronic device 2210. At step 2303, the one or more processors of the electronic device 2210 are initiated using the application 2205 containing the client file 2207 (e.g., using the client file 2207 itself) to provide an encrypted application key (AK_(c)-Enc) as a parameter. At step 2305, the one or more processors of the electronic device 2210 using the application 2205 containing the client file 2207 (e.g., using the client file 2207 itself) to invoke the MTD functions for application operations. MTD functions for application operations may include at least one of rooting, jailbreaking, application integrity evaluation, malware detection, or the like. In a certain embodiment, the MTD functions may include at least one of two modes: synchronous (blocking) checks and/or asynchronous (background) checks. At step 2307, synchronous checks may be completed (e.g., must be completed) before the one or more processors of the electronic device 2210 can continue processing with the application 2205 containing the client file 2207 (e.g., processing the client file 2207 itself). Additionally, or alternatively, at step 2309, asynchronous checks may be completed in parallel with the processing of the application 2205 containing the client file 2207 (e.g., the processing of the client file 2207 itself) using the one or more processors of the electronic device 2210. In either of two modes, if any issues are identified by the one or more processors of the electronic device 2210 (e.g., governed by policies and configured security levels), the execution of the application 2205 containing the client file 2207 may stop (e.g., abort) and return an error message to the application 2205 containing the client file 2207. If no issues are identified, then the one or more processors of the electronic device 2210 processing the application 2205 containing the client file 2207 may determine that the electronic device 2210 is healthy or has no issues (e.g., above/below a threshold rooting level, without malware, no detection of jailbreaking, above a threshold level of application integrity, or the like) and may continue processing of the application 2205 containing the client file 2207. In certain embodiments, the identification of issues by the asynchronous checks can happen at any time or at any step of the methods described herein and the application 2205 containing the client file 2207 may incorporate the results and take action at any point in time or during any step of the methods described herein as appropriate.

For example, at step 2311, the one or more processors of the electronic device 2210 utilizing the application 2205 containing the client file 2207 (e.g., utilizing the client file 2207 itself) may determine whether any issues exist with the electronic device 2210. If the one or more processors of the electronic device 2210 determine that an issue with the electronic device 2210 exists, then, at step 2313, the initialization of the application 2205 containing the client file 2207 (e.g., initialization of the client file 2207 itself) fails (e.g., aborts). If the one or more processors of the electronic device 2210 determine that an issue with the electronic device 2210 does not exist, then, at step 2315, the application 2205 containing the client file 2207 (e.g., the client file 2207 itself) checks (e.g. verifies) whether a UK_(c)-Enc key (e.g., an encrypted user key) exists (e.g., is stored in the client file 2207, is stored in the electronic device 2210). Existence of the UK_(c)-Enc key may indicate that the application 2205 containing the client file 2207 has previously gone through an enrollment process and has a user key distributed to the client file 2207 for local secure storage on the electronic device 2210. At step 2317, if the one or more processors of the electronic device 2210 determines that the UK_(c)-Enc key does not exist, then, at step 2319, method 2400 illustrated in FIG. 24 may be initiated and/or executed. At step 2317, if the one or more processors of the electronic device 2210 determines that the UK_(c)-Enc key does exist, then, at step 2321, method 2700 illustrated in FIG. 27 may be initiated and/or executed.

FIG. 24 illustrates another flow diagram of a method 2400 for network-based key distribution operations according to certain embodiments of the disclosure. Method 2400 may be implemented if, at step 2317 of FIG. 23, the one or more processors of the electronic device 2210 determines that the UK_(c)-Enc key does not exist. FIG. 24 illustrates an example 2400 method implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2400 of FIG. 24, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2400 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

At step 2401, one or more processors of the electronic device 2210 may initiate a bootstrap flow method 2400. At step 2403, the one or more processors of the electronic device 2210 may decrypt the AK_(c)-Enc key from the application 2205 containing the client file 2207 (e.g., from the client file 2207 itself) to obtain (e.g., generate) the AK_(c) and the UUID of the client file 2207 and may send the UUID to the gateway 2255. At step 2405, the gateway 2255 may receive the UUID from the electronic device 2210 and use the UUID to look up and retrieve a corresponding AK_(s) stored on a credential store 2259. At step 2407, the gateway 2255 may receive the corresponding AK_(s) from the credential store 2259 and transmit an acknowledgment of the successful retrieval of the AK_(s) to the electronic device 2210 (e.g., the application 2205 containing the client file 2207, the client file 2207 itself). At step 2409, the electronic device 2210 (e.g., the application 2205 containing the client file 2207, the client file 2207 itself) receives the acknowledgment of the successful retrieval of the AK_(s) from the gateway 2255. At step 2411, the electronic device 2210 (e.g., the application 2205 containing the client file 2207, the client file 2207 itself) initiates an RMAK protocol flow with the gateway 2255. At step 2413, the gateway 2255 receives an indication that the RMAK protocol flow with the electronic device 2210 is initiated. The RMAK protocol flow allows the application 2205 containing the client file 2207 (e.g., the client file 2207 itself) on the electronic device 2210 and the server 2257 (illustrated in FIG. 22) to create a secure application-specific tunnel based on their respective halves of the application key AK. For example, turning back to FIG. 22, a RMAK protocol flow 2271, 2273, 2275 (e.g. a secure application-specific tunnel/channel) provides communication between each of the applications 2205, 2209, and 2013, respectively, on the electronic device 2210 and the gateway 2255. This secure application-specific tunnel is called an application channel 1316 (or primary channel) and exists to protect the data sent using the subsequent method steps of the method 2400.

At step 2415, the electronic device 2210 utilizing the application 2205 containing the client file 2207 (e.g., utilizing the client file 2207 itself) may collect client file heuristics and electronic device parameters (e.g., variant and/or invariant parameters) and send the client file heuristics and electronic device parameters to the gateway 2255. The electronic device 2210 utilizing the application 2205 containing the client file 2207 (e.g., utilizing the client file 2207 itself) may also establish a secure communication session with the gateway 2244 using the application channel 1316 to send the client file heuristics and electronic device parameters to the gateway 2255. At step 2417, the gateway 2255 may receive the client file heuristics and electronic device parameters from the electronic device 2210 and perform the configuration policy checks on the raw device data (e.g., the client file heuristics, the electronic device parameters). If the raw device data passes the configuration policy checks, the gateway 2255 may generate an electronic device fingerprint that is unique to the relationship between the gateway 2255 and the electronic device 2210 (e.g., the client file 2207 in the application 2205 stored in the electronic device 2210). The gateway 2255 may also retrieve the scope of the application 2205, the scope of the electronic device 2210 (if the scope of the application 2205 and the scope of the electronic device 2210 exist), and data privacy keys from the credential store 2259.

At step 2419, the gateway 2255 may generate an application session and an application session scope data privacy key. The gateway 2255 may also generate a device scope data privacy key if the device scope data privacy key was not retrieved. The gateway 2255 may bind the application session to the electronic device fingerprint and send the application session and the electronic device fingerprint, in a session token, along with the retrieved data privacy keys to the electronic device 2210 (e.g., the client file 2207 of the application 2205) over the secure application channel 1316. At step 2421, the electronic device 2210 (e.g., the client file 2207) may receive the application session and the electronic device fingerprint, sent in the session token, along with the retrieved data privacy keys. In certain embodiments, the application session and the electronic device fingerprint, sent in the session token, along with the retrieved data privacy keys may be sent directly to the client file 2207 of the electronic device 2210 without being provided to the application 2205 of the electronic device 2210. At step 2423, the electronic device 2210, using the client file 2207, may signal completion of the initialization process after the electronic device 2210 (e.g., the client file 2207) receives the application session and the electronic device fingerprint, sent in the session token, along with the retrieved data privacy keys. In certain embodiments, the client file 2207 on the electronic device 2210 may signal completion of the initialization process to the application 2205 on the electronic device 2210.

At step 2425, the electronic device 2210 through the application 2205 may execute a user identification flow or process. At step 2427, the user identification flow may include generating a request on a display screen requesting that a user provide a username if an account has been previously established. At step 2429, the username may be sent to the gateway 2255 using a check challenge API. In certain embodiments, if the user does not have an account, the electronic device 2210, through the application 2205, may initiate a full user registration or user KYC function. This process may be designed by the organization and may be outside the scope of the methods described herein (though the concepts described herein may support some out-of-the-box method processes of its own and incorporate some identity verification services that customers can incorporate. Any registration or KYC data being sent to an organization's backend servers can be transmitted securely using the encrypted application channel 1316 (e.g., through the gateway 2255, which can either hand it off to the server 2257 in a basic installation process or pass it on to a backend business service the organization may already have for this purpose. At the end of the verification process, the user may have a user identifier (e.g., a username) which would allow the method to connect back to the aforementioned steps. During the registration process, the user scope data privacy keys may be created and saved on the user record. This would happen during step 2425 or a pre-registration or pre-provisioning time.

At step 2431, the electronic device 2210 through the application 2205 may send the user identifier (e.g., a username) to the gateway 2255 and the gateway 2255 may receive the user identification. The gateway 2255 may lookup the status of the user as well as an existing application and device bindings that may already exist for the user. At step 2433, the gateway 2255 may execute one of the following: 1) if the status indicates that the user is not registered with any existing application and device bindings, then the gateway 2255 may invoke an application flow for an initial device method such as method 2500 illustrated in FIG. 25; 2) if the status indicates that the user is registered and has a user key stored on the server for the user, application, device combination, then the gateway 2255 may invoke a login flow based on server-side key storage method such as method 2800 illustrated in FIG. 28; or 3) if the status indicates that the user is registered and has existing application and device binding, but not for a particular electronic device, then the gateway 2255 may invoke an additional device activation flow method such as method 2900 illustrated in FIG. 29.

FIG. 25 illustrates another flow diagram of a method 2500 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 25 illustrates an example method 2500 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2500 of FIG. 25, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2500 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

The method 2500 of FIG. 25 may be implemented, for example, when the gateway 2255 described at least with respect to step 2433 of method 2400, determines that the looked-up status of the user indicates that the user is not registered with any existing application and device bindings. At step 2501, the gateway 2255, performing one or more network-based key distribution operations, may transmit a message to the management server 2257 instructing the management server 2257 to generate credentials. At step 2503, the management server 2257 may receive the message from the gateway 2255 and generate a split key (e.g., a REL-ID split key, or user key (UK)). The management server 2257 may split the split key into two halves, a server key (UK_(s)) and a client key (UK_(c)). At step 2505, the management server 2257 may generate an activation code (AC) and a validation code (VC). The management server 2257 may use the AC as entropy to generate a key that is subsequently to be used to encrypt the client key of the user key (UK_(c)) creating an encrypted client key (UK_(c)-Enc). A hash of the activation code (AC-Hash) is also created. In certain embodiments, the user provisioning the APIs supported by one or more network-based key distribution operations (e.g., REL-ID) allows the pre-registration process to set the AC to a non-random, known value of the user. This may provide use in enterprise user enrollment processes, or certain consumer self-registration processes, where the AC can become a knowledge-based factor that eliminates the need to send it to the user using an out-of-band mechanism.

At step 2509, the management server 2257 may save the UKs, the UK_(c)-Enc, the AC-Hash, and the VC as part of the user record in the credential store 2259. The management server 2257 may also transmit the AC and the VC out-of-band (e.g., via email, via text message) to the user of the electronic device 2210. The one or more network-based key distribution operations may support various mechanisms, including automatically sending it to the user over email or SMS, and make it available via API calls to registration interfaces that organizations may want to incorporate as part of the process. The management server 2257, after transmitting the activation code and the validation code out of band, may hash the AC. The management server 1157 may store the hashed AC in a memory (e.g., a credential store 2259) and the VC is stored in the clear. As discussed herein, the out-of-band delivery may be skipped as requested by a customer's user registration and enrollment process.

At step 2511, the management server 2257 may transmit a request message (e.g., an API response) to the gateway 2255 for the electronic device 910 that requests the AC and the VC for use by the application 2205 (or the request message can supply the knowledge based AC based on the customer enrollment process). At step 2513, the gateway 2255 receives the request message and transmits the request message using the application channel 1316 to the electronic device 2210. At step 2515, the client file 2207 of the electronic device 2210 receives the request message. At step 2517, the application 2205 of the electronic device 2210 receives the request message. At step 2519, the electronic device 2210 using the application 2205 may display the VC and asks a user to enter the corresponding AC. This can be done by electronic device 2210 receiving (e.g., entering into the electronic device 2210 by a user) a clear text code providing the knowledge-based AC that the enterprise set as part of the account provisioning flow, or scanning a generated QR code version of the AC. In certain embodiments, this can be automated to avoid the user having to enter or type anything (e.g., a silent mode). This may be configured in the management server 2257. The application 2205 of the electronic device 2210 may provide the AC to the client file 2207 using an API (e.g., a checkchallenge API).

At step 2521, the electronic device 2210 using the client file 2207 may hash the AC and send the VC and the hashed AC to the gateway 2255 via the application channel 1316. At step 2523, the gateway 2255 may receive the VC and the hashed AC from the electronic device 2210. At step 2525, the server 2257 may receive the hashed AC from the gateway 2255 and transmit the hashed AC to the credential store 2259 for validation of the hashed AC. If the validation passes, then, at step 2527, the server 2257 may retrieve the UK_(c)-Enc from the credential store 2259 and transmit the UK_(c)-Enc to the gateway 2255. At step 2529, the gateway 2255 may transmit the UK_(c)-Enc to the electronic device 2210 through the application channel 1316 for reception by the client file 2207. At step 2531, the client file 2207 may receive the UK_(c)-Enc from the gateway 2255 and decrypts the UK_(c)-Enc using the AC. At step 2533, the application 2205 containing the UK_(c) may extract the UUID from the UK_(c) and send the UUID to the gateway 2255 through the application channel 1316. At step 2535, the gateway 2255 may receive the UUID and look up the UUID in the credential store 2259. At step 2537, the gateway 2255 may retrieve the correlating UK_(s). At step 2537, the gateway 2255 may transmit an acknowledgment of being able to retrieve the UK_(s) to the electronic device 2210 for action (e.g., execution) by the client file 2207 through the application channel 1316. At step 2539, the electronic device 2210 may receive the acknowledgment that the gateway 2255 is able to retrieve the UK_(s). At step 2541, with the client file 2207 holding the UK_(c), the electronic device 2210 may utilize the RMAK protocol to create a user channel 1542 (e.g., a secure channel, secondary channel) with the gateway 2255. At step 2543, the gateway 2255 may receive an indication of the creation of the user channel 1542 and may receive a user identification, an application identification, a device identification. At step 2545, upon the successful creation of the user channel 1542, the server 2257 may create a binding of the server half key (UK_(s)) to the user, the application 2205 (based on the UUID) and the electronic device 2210, and save it to the credential store 2259. At step 2547, the server 2257 may communicate the binding indication to the gateway 2257. At step 2549, the gateway 2255 may receive the binding indication.

FIG. 26 illustrates another flow diagram of a method 2600 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 26 illustrates an example method 2600 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2600 of FIG. 26, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2600 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

The method 2600 of FIG. 26 may be implemented, for example, when the gateway 2255, described at least with respect to step 2549 of method 2500, receives the binding indication. For example, step 2601 may be the same as or at least similar to step 2549 illustrated in FIG. 25. At step 2603, the gateway 2255 may return status of the credentials being saved to the client file 2207 along with the supported authentication challenges, which may immediately trigger the SDK (e.g., the client file 2207) to determine the authentication challenges supported by the particular application build and electronic device type and ask for the user to register the authentication. This may depend on user authentication models supported by the application 2205. At step 2605, the electronic device 2210 through the client file 2207 may receive from the gateway 2255 the status of the credentials being saved through the user channel 1542. At step 2607, the electronic device 2210 through the application 2205 registers the user authentication. In the case of a device local biometric, the client file 2207 may generate a random token that gets stored in the secure hardware storage of the electronic device when the user registers their local biometric. The random token may be retrievable when initiating the device local biometric. The random token may be an entropy provided by the client file 2207. In the case of a server-side biometric, the user registers in the biometric (e.g., through the electronic device 2210, through the application 2205 on the electronic device 2210, through the client file 2207 on the electronic device 2210) or validates the existing biometric. Successful registration/validation by the biometric authentication service may return a response that is consistent each time a user authenticates and may be the entropy provided to the client file 2207. In the case of a password (e.g., a passcode, a pin), a user may either register a new password or validate an existing password. This may be useful if supporting existing passwords are based authentication services. A hashed password may be the entropy provided to the client file 2207. To support this, the system can integrate with enterprise LDAP/AD/standards-based authentication services and/or stores. In the case of a fast identity online (FIDO) authenticator biometric, a user may register their FIDO biometric in a FIDO authenticator. The client file 2207 may provide a randomly generated string to be signed. A successful registration may supply back the signed version string. The client file 2207 may use the signed string as the entropy. In the case of a federated authentication (e.g., SAML, OpenID Connect, Facebook login, or the like) the application to 205 may take the user through the authentication process and may receive back an authentication token which may be provided to the client file 2207. The authentication token may be used to create an associated random to be used as entropy.

At step 2609, the client file 2207 may generate a digital signing key (DSK). At step 2611, the client file 2207 may encrypt the UK_(c) with the entropy received from the user (e.g., the electronic device 2210) as step 2607 using the PBKDF2 algorithm. The client file 2207 may determine how to store the UK_(c)-Enc. For example, if secure hardware storage is available, the client file 2207 may see the entropy in the secure hardware storage and the UK_(c)-Enc in the application storage. As another example, if secure work storage is not available, the client file 2207 may send the UK_(c)-Enc to the gateway 2255 over the user channel 1542 (e.g., the secure channel) so that the gateway 2255 stores UK_(c)-Enc in the credential store 2259. At step 2613, the client file may send a public key for the digital signing key (DSK_(pub)) to gateway 2255 over the user channel 1542 (e.g., the secure channel). As step 2615, the server 2257 may save the digital signing key as part of the user identification, application identification, electronic device identification binding record. At step 2617, the server 2257 may store the saved digital signing key in the credential store 2259. At step 2619, the gateway 255 may create a user session and may bind the user session to the combination of the user identification, application identification, electronic device identification binding and session scope data privacy keys to the client file 2207 over the user channel 1542 (e.g., the secure channel). At step 2621, client file 2207 may encrypt the DSK using the combination of the user identification, application identification, electronic device identification binding and session scope data privacy keys. The client file 2207 may store the combination to the application storage of the electronic device 2210. As step 2623, the client file 2207 may indicate to the application 2205 that the authentication is complete and that the application 2205 may now use the user channel for performing secure tunneling API calls to the backend application service that sits behind the gateway 2255.

FIG. 27 illustrates another flow diagram of a method 2700 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 27 illustrates an example method 2700 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2700 of FIG. 27, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2700 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2800 illustrated in FIG. 28, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

The method 2700 of FIG. 27 may be implemented such that when client file 2207 finds that the UK_(c)-Enc exists, client file 2207 may indicate that the application 2205 has previously gone through the enrollment process and has had a user key distributed to the client file 2207 for local (on-device) secure storage. This means that normal login can proceed. For example, step 2701 may be the same as or at least similar to step 2321 of method 2300 illustrated in FIG. 23. Subsequently, at step 2703, the client file 2207 may retrieve the UK_(c)-Enc from its storage location and decrypt the UK_(c)-Enc using secured storage APIs and a core SDK. The client file 2207 may also decrypt the AK_(c)-Enc to obtain the AK_(c) and the application UUID. With the application 2205 holding the UK_(c) the application to 205 may extract the UUID_(u) from the UK_(c) and send it to the gateway 2255. In certain embodiments, if more than one UK_(c)-Enc is retrieved (implying that more than one user is activated on the electronic device 2210 and the application to 2205), then the client file 2207 (e.g., the SDK) may display an account chooser that allows the user to pick which user wants to login, selecting the particular UK_(c)-Enc. The implementation of the account chooser may include using a local PIN for protection.

At step 2705, the gateway 2255 may look up the UUID_(u) in the credential store 2259 and retrieve the associated bindings. At step 2707, the client file 2207 (e.g., the SDK) may initiate the RMAK protocol, and the client file 2207 (e.g., SDK) and the gateway 2255 may follow the RMAK protocol to create a user identification, application identification, electronic device identification bound specific tunnel (e.g., user channel 1542). The tunnel may not yet be active. At step 2709, the client file 2207 (e.g., the SDK) may collect all the required application heuristics and device parameters (both variant and invariant). The client file 2207 (e.g., the SDK) may spread private key from AK_(c) and may use it to sign the UUID_(a), the application heuristics, and the device parameters. The client file 2207 (e.g., the SDK) may then send the signed elements to the gateway 2255 over the secure channel.

At step 2711, the gateway 2255 may perform figurative policy checks on the wrong device data. The gateway 2255 may also obtain the public key from the AK_(s) and use the public key to validate the signature on the signed elements to confirm that the client file 2205 has the appropriate AK_(c). The gateway 2255 may retrieve the user identification, application identification, electronic device identification, and scope data privacy keys from the credential store 2259. At step 2713, if the policy checks are passed, the gateway 2255 may generate a device fingerprint and check the user status as well as the user identification, application identification, electronic device identification binding. If the user identification, application identification, electronic device identification bindings is not confirmed, the gateway 2255 may initiate a correction flow to indicate that something about the electronic device 2210 has changed to alter the fingerprint. Otherwise this may create a temporary user session and bind it to the combination of the electronic device identification and the application identification, and return the temporary session token and the user identification, application identification, electronic device identification, scope data privacy keys to the client file 2207 (e.g., the SDK) over the secure channel.

At step 2715, as part of the temporary session token, the client file 2207 (e.g., the SDK) may also retrieve the authentication challenge required (based on what the user registered with) and a random token in case it is needed by the authentication challenge. As step 2717, based on the authentication challenge required, the appropriate user interface of the electronic device 2210 and/or the client file 2207 (e.g., the SDK) may be triggered to authenticate the user. This could be device local authentication (e.g., touch ID, face ID, fingerprint ID, pattern ID) or server-based authentication (e.g., server-based biometric authentication, password authentication, pin authentication). At step 2719, a user may authenticate themselves using an appropriate method. In the case of device local authentication, the successful verification of the local authentication may unlock a token that is sent back to the REL-ID Server as the user credential. In the case of server-based authentication, the actual credential (password, PIN or biometric template hash collected as required by the server-based authentication service) is sent back to the server 2259 as the user credential. It could also be an API call made to the server-based authentication service that is tunneled over the user channel to the gateway 2255, which then forwards it to the authentication service (local or internet-based).

At step 2721, the server 2257 may validate the user credential provided (either on its own, or through an integration with the server-based authentication service) and receive the result. At step 2723, if the authentication does not succeed, then the REL-ID login process is aborted, and the user session is stopped. Otherwise, at step 2725, the server 2257 may retrieve the user identification, the electronic device identification, the application identification, and scope data privacy keys, and generate a session scope data privacy key. This up-levels the temporary user session to a complete user session. At step 2727, the server 2257 may return the session token and the user identification, the electronic device identification, the application identification, and scope data privacy keys, to the client file 2207 (e.g., the SDK) over the secure channel. At step 2729, the client file 2207 (e.g., the electronic device 2210 or a processor of the electronic device 2210 may execute the client file 2207) may inform the application 2205 that authentication was successful and that it can now use the user channel for performing secure tunneling of API calls to the backend application service that sits behind the gateway 2255. At step 2731, the user channel is ready for use.

FIG. 28 illustrates another flow diagram of a method 2800 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 28 illustrates an example method 2800 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2800 of FIG. 28, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2800 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2900 illustrated in FIG. 29, or one or more steps of method 3000 illustrated in FIG. 30.

The method 2800 of FIG. 28 may be implemented when a status indicates that the user is registered and has a user key stored on the server for the user, application, device combination as described at step 2433 of method 2400 illustrated in FIG. 24. In method 2800, the gateway 2255 may invoke a login flow based on server-side key storage method. Step 2801 may be the same as or at least similar to step 2433 of method 2400 illustrated in FIG. 24, when a status indicates that the user is registered and has a user key stored on the server for the user, application, device combination. Subsequently, at step 2803, the gateway 2255 may enter this flow because it has confirmed both the user status as well as the user identification, application identification, and electronic device identification bindings. At step 2805, the gateway 2255 may retrieve both halves of the User Key, UK_(s) and UK_(c)-Enc, for the user identification, application identification, and electronic device identification bindings. At step 2807, the gateway 2255 may return the response to the client file 2207 (e.g., the SDK), which informs the application 2205 that server-based authentication is required. At step 2809, the application may initiate the server-based authentication flow that collects the credentials from the user (biometric data or password) and tunnels the authentication call to the gateway 2255 over the application channel 1316. This could also be an API call made to the server-based authentication service that is tunneled over the application channel 1316 to the gateway 2255, which then forwards it to the authentication service (local or internet-based).

At step 2811, an identity store adapter (ISA) 2290 configured on the gateway 2255 may invoke authentication on the configured server-side authentication service (this could be REL-IDs own authentication service, the organizations own on-premises authentication service, or a cloud-based authentication service). The ISA may receive back the authentication result. At step 2813, if applicable, the gateway 2255 may use the authentication result to extract the authentication result entropy (could come from the authentication service or from gateway 2255 itself). The gateway 2255 may return the authentication result, the authentication result entropy, and UK_(c)-Enc to the client file 2207 (e.g., the SDK). At step 2815, the client file 2207 (e.g., the SDK) may receive the UK_(c)-Enc and decrypt the UK_(c)-Enc using the entropy it has received. At step 2817, with the client file 2207 holding UK_(c), the client file 2207 may extract UUID_(u) from it and sends it to the gateway 2255. At step 2819, the gateway 2255 may look up the UUID_(u) in the credential store 2259 and retrieve the associate bindings. The gateway 2255 may also retrieve the user identification, application identification, electronic device identification, and scope data privacy keys from the credential store 2259. At step 2821, the client file 2207 (e.g., the SDK) may initiate the RMAK protocol. The client file 2207 and the gateway 2255 may follow the RMAK protocol to create a secure user identification, application identification, electronic device identification-specific tunnel. This tunnel may be the user channel 1542 (e.g., secondary channel). At step 2821, the user channel 1542 may not be active yet.

At step 2823, the gateway 2255 may request the creation of a user session. At step 2825, the gateway 2255 may perform any configured policy checks. At step 2827, the gateway 2255 may create a user session and bind the user session to the combination of user identification, application identification, electronic device identification. The gateway 2255 may then return the session token to the client file 2207 (e.g., the SDK) over the secure channel (e.g., the user channel 1542). At step 2829, the client file 2207 (e.g., the SDK) may inform the application 2205 (e.g., the application 2205 on the electronic device 2210) that authentication was successful and that application 2205 (e.g., the application 2205 on the electronic device 2210). At step 2831, the application 2205 (e.g., the electronic device 2210 executing the application 2205) can use the user channel 1542 for performing secure tunneling of API calls to the backend application service that sits behind the gateway 2255.

FIG. 29 illustrates another flow diagram of a method 2900 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 29 illustrates an example method 2900 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 2900 of FIG. 29, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 2900 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, or one or more steps of method 3000 illustrated in FIG. 30.

The method 2900 of FIG. 29 may be implemented when a status indicates that a user is registered and has existing application and device binding, but not for a particular electronic device, so that the gateway 2255 may invoke an additional device activation flow method as describe in step 2433 of method 2400 illustrated in FIG. 24. Step 2901 may be the same as or at least similar to step 2433 of method 2400 illustrated in FIG. 24, when a status indicates that a user is registered and has existing application and device binding, but not for a particular electronic device, so that the gateway 2255 may invoke an additional device activation flow method. At step 2903, the gateway 2255 may send a REL-IDverify notification to the user's previously registered and bound electronic device(s) 2210. The REL-IDverify notification may be sent over an APNS/FCM channel 1057. As step 2905, the gateway 2255 may save the REL-IDverify notification as sent in a waiting state in the credential store 2259. At step 2907, the electronic device 2210 may receive the notification, open the application 2205, and set up the user channel 1542. In this case, the electronic device 2210 may have been previously registered. Viewing the REL-IDverify notification on the electronic device 2210 requires the user doing a simple but fully secure REL-ID authenticate-then-connect flow (as outlined in the flows above). At step 2909, the application 2205 may invoke the client file 2207 to retrieve notifications, which retrieves them from the gateway 2255 (which retrieves them from the credential store 2259) and returns them to the client file 2207, which returns them to the application 2205. At step 2911, the electronic device 2210 may use the application 2205 to display the REL-IDverify notification, which asks the user if they are trying to log in on a new device, and provides the relevant device information regarding it (captured from the device fingerprinting, like type, IP, location, or the like), asking the user to approve or reject. At step 2913, the electronic device 2210 may receive an “approve” click from a user. The electronic device 2210 may send the response to the gateway 2255. At step 2915, the gateway 255 may record (e.g., save) the response. At step 2917, the server 2257 may trigger secondary device activation. At this point, the flow shifts to interaction with the new device being registered.

FIG. 30 illustrates another flow diagram of a method 3000 for network-based key distribution operations according to certain embodiments of the disclosure. FIG. 30 illustrates an example method 3000 implemented by one or more processors of an electronic device 2210 and/or one or more gateways 2255, performing one or more network-based key distribution operations, according to certain embodiments of this disclosure. Although certain details will be provided with reference to the method 3000 of FIG. 30, it should be understood that other embodiments may include more, less, or different method steps. For example, one or more steps of method 3000 may be incorporated into one or more steps of method 1300 illustrated in FIG. 13, one or more steps of the method 1400 illustrated in FIG. 14, one or more steps of method 1500 illustrated in FIG. 15, one or more steps of method 1600 illustrated in FIG. 16, one or more steps of method 1700 illustrated in FIG. 17, one or more steps of method 1800 illustrated in FIG. 18, one or more steps of method 1900 illustrated in FIG. 19, one or more steps of method 2000 illustrated in FIG. 20, one or more steps of method 2300 illustrated in FIG. 23, one or more steps of method 2400 illustrated in FIG. 24, one or more steps of method 2500 illustrated in FIG. 25, one or more steps of method 2600 illustrated in FIG. 26, one or more steps of method 2700 illustrated in FIG. 27, one or more steps of method 2800 illustrated in FIG. 28, or one or more steps of method 2900 illustrated in FIG. 29.

The method 3000 illustrated in FIG. 30 may be a continuation of method 2900 illustrated in FIG. 29. For example, step 2917 of method 2900 illustrated in FIG. 29 may be the same as or at least similar to step 3001 of method 3000 illustrated in FIG. 30. At step 3001, the server 2257 may trigger or initiate secondary device activation. At step 3003, the server 2257 may generate a new REL-ID split User Key UK. At step 3005, the server 2257 may bind the server half (UK_(s)) to a username, an application 2205 (e.g., based on an application UUID_(a)) and the new device (e.g., based on its device fingerprint) and saves it in the credential store 2259. At step 3007, the server 2257 may encrypt UK_(c) with the application session scope data privacy key. At step 3009, the gateway 2255 may receive UK_(c)-Enc from the server 2257 and may return the UK_(c)-Enc to the client file 2207 over the application channel 1316. At step 3011, the client file 2207 may decrypt the UK_(c)-Enc received using the application session scope data privacy key. At step, 3013, with the client file 2207 holding the UK_(c), the client file 2207 may extract a UUID_(u) from the UK_(c) and send the UUID_(u) to the gateway 2255. At step 3015, the gateway 2255 may look up the UUID_(u) in the credential store 2259 and retrieve the UK_(s). At step 3017, with the client file 2207 holding the UK_(c) and the gateway 2255 holding the corresponding UK_(s), a secure channel is created following the RMAK protocol. The secure channel may be the user channel 1542 (e.g., secondary channel). At step 3019, on the successful creation of the user channel 1542, the server 2257 may create a binding of the server half key (UK_(s)) to the user of the electronic device 2210, the application 2205 (e.g., based on UUID_(a)) and the electronic device 2210 (e.g., based on the electronic device fingerprint) and save the binding to the credential store 2259. At step 3021, the remaining steps may be the same as steps 2603 to 2625 of the activation flow on an initial electronic device 2210 described herein with respect to method 2600 illustrated in FIG. 26.
